Sponsored by the Infrastructure Resilience Division of ASCE During 2010 and 2011, a sequence of strong earthquakes affected two communities in the province of Canterbury on the South Island of New Zealand. Christchurch, which is the second largest city in New Zealand, and Kaiapoi, in the Waimakariri District, suffered the greatest damage. Tens of thousands of buildings required demolition or significant reconstruction. Soil liquefaction, which was the leading cause of damage to lifelines, dictated that some areas of Christchurch could never be rebuilt. This report describes in detail the performance of lifeline systems in the Christchurch area, as observed during visits by an Earthquake Investigation Committee sent by ASCE's Technical Council on Lifeline Earthquake Engineering (TCLEE). This TCLEE Monograph discusses the following lifelines with recommendations for improving performance: electric power systems; telecommunications systems; water and wastewater infrastructure; gas and liquid fuel facilities; the port of Lyttelton; and transportation infrastructure, including the airport, roads and bridges, and railways. General seismology of the event, geotechnical features of the area, and applicable seismic codes are described. Other relevant issues, such as fire following the earthquakes, levees, lifeline interdependence, effects on building stock, damage to nonstructural building components, and debris management are considered. TCLEE 41 will be of interest to civil engineers, emergency managers and planners, and government officials charged with improving resilience of lifeline infrastructure systems during earthquakes, especially those characterized by significant soil liquefaction.

3. Duration of earthquake ground motion [electronic resource] : influence on structural collapse risk and integration in design and assessment practice [2016] Online
- Book
- 1 online resource.
Amplitude, frequency content, and duration are widely recognized as the key characteristics of earthquake ground motions that influence structural response. Yet, in current structural design and assessment practice, ground motions are often explicitly characterized by just their pseudo acceleration response spectra-which quantify their amplitude and frequency content-while duration is commonly relegated to implicit, qualitative consideration. This study evaluates the need to explicitly consider duration, in addition to response spectra, in structural design and assessment. The influence of duration on structural collapse capacity is investigated by numerically simulating the response of structures under short and long duration ground motions. Realistic nonlinear structural models that incorporate the in-cycle and cyclic deterioration of the strength and stiffness of structural components, and the destabilizing P-Delta effect of gravity loads, are employed to successfully detect the effect of duration. Long duration ground motions from recent large magnitude earthquakes, like the 2008 Wenchuan (China, Mw 7.9), 2010 Maule (Chile, Mw 8.8), and 2011 Tohoku (Japan, Mw 9.0) earthquakes, are used in the analyses. The effect of response spectral shape is controlled for by selecting sets of short and long duration ground motions with similar response spectra, and by employing appropriate statistical tools to post-process the analysis results. Significant duration, Ds, is identified as the duration metric best suited for use in structural design and assessment, since it is amenable to incorporation in a vector intensity measure alongside the response spectrum, and is an efficient predictor of structural collapse capacity. Response spectral shape and duration are together shown to be capable of explaining around 80% to 85% of the variance in the collapse intensities of ground motions used to analyze 51 reinforced concrete moment frame buildings. Response spectral shape or duration alone, are capable of explaining a significantly smaller fraction of the variance in the collapse intensities. This highlights the need to explicitly consider both response spectra and duration in structural design and assessment, and indicates that the additional consideration of other ground motion characteristics is likely to produce diminishing returns. A procedure based on the generalized conditional intensity measure (GCIM) framework is developed to compute source-specific conditional probability distributions of the durations of the ground motions anticipated at a site. Commonly used ground motion databases-like the PEER NGA-West2 database-are currently dominated by short duration ground motions, since many more low and moderate magnitude earthquakes (6.0 < Mw < 7.5) have been recorded in recent history than large magnitude interface earthquakes (Mw ~ 9.0). Selecting records from the PEER NGA-West2 database without explicitly considering duration is, therefore, shown to result in the unconservative underestimation of structural collapse risk at sites located near active subduction zones, that are susceptible to long duration ground motions from large magnitude interface earthquakes. For example, selecting records from the PEER NGA-West2 database to explicitly match only conditional spectrum targets, and not duration targets, is shown underestimate the mean annual frequency of collapse of an eight-story reinforced concrete moment frame building by 29% when located in Seattle (Washington) and 59% when located in Eugene (Oregon). A relatively small influence of duration is observed at San Francisco (California), which is likely to experience short to moderate duration ground motions from shallow crustal earthquakes. The prevalent practice of implicitly accounting for duration using causal parameters like rupture mechanism, earthquake magnitude, source-to-site distance, and site Vs30, is shown to result in the selection of records that poorly match conditional spectrum and duration targets, thereby producing biased collapse risk estimates. Strategies are proposed to explicitly consider duration, in addition to response spectral shape, in the analysis procedures contained in the following standards for structural performance assessment and design: (i) the FEMA P-58 seismic performance assessment methodology; (ii) the FEMA P695 methodology to quantify seismic performance factors; and (iii) the ASCE 7-16 seismic design provisions. The effect of duration is incorporated in multiple stripe analysis (MSA) by selecting records to match duration targets, in addition to conditional spectrum targets, at each intensity level. A structural reliability framework incorporating response spectral shape (quantified by a scalar parameter called SaRatio) and duration (quantified by Ds), is developed to compute a hazard-consistent collapse fragility curve by post-processing the results of an incremental dynamic analysis (IDA) conducted using a generic record set. The procedure first involves defining a failure surface by fitting a multiple linear regression model to the computed ground motion collapse intensities using SaRatio and Ds as predictors. The probability of collapse at an intensity level is then computed by integrating the site-specific target distributions of SaRatio and Ds conditional on that intensity level, over the failure domain. A simplified method is additionally developed to efficiently compute just the hazard-consistent median collapse capacity. The effects of response spectral shape and duration are incorporated in ASCE 7-16's equivalent lateral force procedure by developing site and structural system-specific adjustment factors for the design base shear. These adjustment factors are computed based on the site-specific conditional median SaRatio and Ds targets and the sensitivity of the structure to the effects of response spectral shape and duration. The use of these adjustment factors ensures a more uniform distribution of structural collapse risk over different geographical regions, and between different structural systems. Sample calculations indicate that a 1s reinforced concrete moment frame building in San Francisco would need to be designed to a base shear that is 43% higher than the value used in current practice to maintain parity with a similar structure designed at a reference site, chosen here to be Los Angeles (California). A similar structure in Eugene would need to be designed to a base shear that is 67% higher. ASCE 7-16's nonlinear response history analysis procedure requires analyzing structures at the risk-target maximum considered earthquake (MCER) intensity level, at which a significant effect of duration on peak story drift ratio is unlikely to be observed. Hence, the imposed acceptance criteria are unlikely to reliably capture the effect of duration. It is, therefore, recommended that the selected records be scaled to an MCER level modified by a duration adjustment factor, analogous to the one developed for the equivalent lateral load procedure. The explicit central difference time integration scheme is proposed as a robust and efficient alternative to commonly used implicit schemes, like the Newmark average acceleration scheme, which often suffer from numerical non-convergence issues when used to simulate the dynamic response of nonlinear structural models, especially when simulating response under long duration ground motions. Its robustness stems from its non-iterative nature, while its efficiency is a consequence of the requirement to factorize a linear combination of only the mass and damping matrices at each time step. The use of a constant damping matrix, therefore, ensures that the matrix factorization needs to be performed just once for the entire analysis. It is shown to be more efficient than implicit schemes when conducting IDA in parallel, despite the limit on the maximum time step imposed by its stability criterion. Its benefits are believed to outweigh a few additional steps involved during model creation, including the assignment of mass to all degrees of freedom. Finally, efficient parallel algorithms are developed to conduct MSA and IDA on multi-core computers and distributed parallel clusters, to enable the use of these otherwise computationally intensive analysis techniques in research and practice.

"A truly welcome and refreshing study that puts earthquake impact on history into a proper perspective" --Amos Nur, Emeritus Professor of Geophysics, Stanford University, California, and author of Apocalypse: Earthquakes, Archaeology, and the Wrath of God. Since antiquity, on every continent, human beings in search of attractive landscapes and economic prosperity have made a Faustian bargain with the risk of devastation by an earthquake. Today, around half of the world's largest cities - as many as sixty - lie in areas of major seismic activity. Many, such as Lisbon, Naples, San Francisco, Tehran and Tokyo, have been severely damaged or destroyed by earthquakes in the past. But throughout history, starting with ancient Jericho, Rome and Sparta, cities have proved to be extraordinarily resilient: only one, Port Royal in the Caribbean, was abandoned after an earthquake. Earth-Shattering Events seeks to understand exactly how humans and earthquakes have interacted, not only in the short term but also in the long perspective of history. In some cases, physical devastation has been followed by decline. But in others, the political and economic reverberations of earthquake disasters have presented opportunities for renewal. After its wholesale destruction in 1906, San Francisco went on to flourish, eventually giving birth to the high-tech industrial area on the San Andreas fault known as Silicon Valley. An earthquake in Caracas in 1812 triggered the creation of new nations in the liberation of South America from Spanish rule. Another in Tangshan in 1976 catalysed the transformation of China into the world's second largest economy. The growth of the scientific study of earthquakes is woven into this far-reaching history. It began with a series of earthquakes in England in 1750. Today, seismologists can monitor the vibration of the planet second by second and the movement of tectonic plates millimetre by millimetre. Yet, even in the 21st century, great earthquakes are still essentially 'acts of God', striking with much less warning than volcanoes, floods, hurricanes and even tornadoes and tsunamis.

6. High-friction sliding seismic isolation for enhanced performance of light frame structures during earthquakes [electronic resource] [2016] Online
- Book
- 1 online resource.
The primary objectives of this research are to develop an isolation system geared towards light frame structures, and to demonstrate that seismic isolation can be both economical and highly effective for light-frame residential construction. Experience from past earthquakes has shown that light frame residential houses in the United States typically pose a low collapse risk, but they are susceptible to damage that can lead to significant financial loss and displacement of residents. This dissertation develops a low-cost seismic isolation system that balances the tradeoffs between isolator displacement demands and base shear force demands through a high-friction sliding system. The isolation system consists of high-density polyethylene (HDPE) sliders on a flat or an upward concave galvanized steel sliding surface, with a sliding coefficient of friction between 0.15 and 0.25 at the isolation interface. The inherent strength and low mass of light frame residential construction allows for a high-friction isolation system to effectively eliminate superstructure damage during even large earthquakes. Parametric studies show that high friction interfaces reduce isolation displacement demands. Isolator sliding material and component tests have been conducted to characterize velocity and pressure dependent interface friction properties of the sliding isolators. New data is provided on low-pressure (2 MPa to 7 MPa) friction coefficients for HDPE and polytetrafluoroethylene (PTFE) sliding on different finished steel surfaces. Proof-of-concept shaking table tests of a full-scale light framed isolated two-story house have been conducted. Results of these tests have (a) confirmed that the isolation system can effectively eliminate damage to the light frame superstructure under repeated severe earthquake ground shaking (b) validated nonlinear computer models to determine sliding isolator demands and superstructure force demands, and (c) demonstrated the constructability and economic practicality of the proposed details for the foundation and wood-framed first floor isolation platform. Numerous findings regarding the behavior of isolated light frame structures are reported herein. The superstructure of an isolated house has a dynamic response during shaking causing higher normalized forces in the superstructure than at the isolation level. Superstructure seismic coefficients are recommended to be 1.8 times the coefficient of friction in the flat sliding system, and 1.2 times the normalized isolation force (assuming rigid body response) in the dish system, to achieve a 20% probability of the induced forces greater than design forces at MCE intensity shaking. The inclusion of the vertical component of the ground motion is shown to not significantly affect isolation response in high friction sliding systems, however, there can be large increases in superstructure and isolator force demands. While using velocity and pressure-dependent friction models can affect the sliding isolation response of systems subjected to individual ground motions, Coulomb friction is found to be sufficient for response prediction when looking at a suite of records. The controlling design variable for seismic isolation systems is the peak isolation displacement. Typically, traditional isolation systems with low yield force and high restoring stiffness are assumed to have an effective period, based on the secant stiffness at the expected displacement. This period is used to infer the seismic displacement demands on the isolator, using the spectral displacements at the assumed period. For a high-friction low-restoring sliding system, the effective period is sensitive to the expected displacement. Additionally, these isolation systems accumulate displacement through ratcheting-type behavior, controlled by the friction properties of the isolation system, rather than exhibiting harmonic-type response as would an equivalent linear system with an effective period. Risk-based methods for determining isolation displacements rely on an assumed period of the isolation system as well. Using the conditional spectrum when scaling records to have the same spectral acceleration at the assumed period and matching the expected median and dispersion of spectral acceleration away from the assumed period results in large dispersion in isolation displacements because spectral ordinates, which are based on linear analysis, do not correspond to nonlinear isolation response. Alternative intensity measures that account for the aspects of the ground motion and sliding system that lead to large isolation displacements are required to make robust predictions of isolation displacements. A new ground motion intensity measure for high friction sliding systems is derived herein from closed-form solutions for the peak sliding displacement of a rigid block subjected to simple pulses. The new intensity measure is analogous to the extra incremental ground velocity of the pulse beyond what it would take to yield the system times the duration of the pulse and is termed the Effective Incremental Ground Velocity (EIGV). EIGV is effective for predicting peak sliding displacements for high friction systems because the large sliding excursion in high friction systems is typically similar in magnitude to the overall peak isolation displacement, which can be captured by a pulse intensity measure. A first generation set of ground motion prediction equations are offered for conducting probabilistic seismic hazard analysis using EIGV, which in term can be used to generate isolation displacement demand curves, better informing design decisions.

Numerous findings regarding the behavior of isolated light frame structures are reported herein. The superstructure of an isolated house has a dynamic response during shaking causing higher normalized forces in the superstructure than at the isolation level. Superstructure seismic coefficients are recommended to be 1.8 times the coefficient of friction in the flat sliding system, and 1.2 times the normalized isolation force (assuming rigid body response) in the dish system, to achieve a 20% probability of the induced forces greater than design forces at MCE intensity shaking. The inclusion of the vertical component of the ground motion is shown to not significantly affect isolation response in high friction sliding systems, however, there can be large increases in superstructure and isolator force demands. While using velocity and pressure-dependent friction models can affect the sliding isolation response of systems subjected to individual ground motions, Coulomb friction is found to be sufficient for response prediction when looking at a suite of records. The controlling design variable for seismic isolation systems is the peak isolation displacement. Typically, traditional isolation systems with low yield force and high restoring stiffness are assumed to have an effective period, based on the secant stiffness at the expected displacement. This period is used to infer the seismic displacement demands on the isolator, using the spectral displacements at the assumed period. For a high-friction low-restoring sliding system, the effective period is sensitive to the expected displacement. Additionally, these isolation systems accumulate displacement through ratcheting-type behavior, controlled by the friction properties of the isolation system, rather than exhibiting harmonic-type response as would an equivalent linear system with an effective period. Risk-based methods for determining isolation displacements rely on an assumed period of the isolation system as well. Using the conditional spectrum when scaling records to have the same spectral acceleration at the assumed period and matching the expected median and dispersion of spectral acceleration away from the assumed period results in large dispersion in isolation displacements because spectral ordinates, which are based on linear analysis, do not correspond to nonlinear isolation response. Alternative intensity measures that account for the aspects of the ground motion and sliding system that lead to large isolation displacements are required to make robust predictions of isolation displacements. A new ground motion intensity measure for high friction sliding systems is derived herein from closed-form solutions for the peak sliding displacement of a rigid block subjected to simple pulses. The new intensity measure is analogous to the extra incremental ground velocity of the pulse beyond what it would take to yield the system times the duration of the pulse and is termed the Effective Incremental Ground Velocity (EIGV). EIGV is effective for predicting peak sliding displacements for high friction systems because the large sliding excursion in high friction systems is typically similar in magnitude to the overall peak isolation displacement, which can be captured by a pulse intensity measure. A first generation set of ground motion prediction equations are offered for conducting probabilistic seismic hazard analysis using EIGV, which in term can be used to generate isolation displacement demand curves, better informing design decisions.

13. Code and data supplement for "Ground motion selection for simulation-based seismic hazard and structural reliability assessment." [2015] Online
This page provides data and code to document the referenced paper, which examines four methods by which ground motions can be selected for dynamic seismic response analyses of engineered systems when the underlying seismic hazard is quantified via ground motion simulation rather than empirical ground motion prediction equations. Even with simulation-based seismic hazard, a ground motion selection process is still required in order to extract a small number of time series from the much larger set developed as part of the hazard calculation. Four specific methods are presented for ground motion selection from simulation-based seismic hazard analyses. One of the four methods provides a ‘benchmark’ result (i.e. using all simulated ground motions), enabling the consistency of the other three more efficient selection methods to be addressed.

14. Design of Composite RCS Special Moment Frames [2015] Online
This document was developed to assist practicing engineers in the design of Composite Special Moment Frame (C-SMF) systems utilizing reinforced concrete columns and steel beams (known as Composite RCS frames). These systems utilize the intrinsic advantages of each material which are optimized in resisting the applied loads.
Seismic design requirements for C-SMF systems are included in ASCE 7 (2010) and AISC 341 (2010). These system-level requirements are supported by research and other documents on the design and detailing of beam-column connections between the steel beams and concrete (or encased composite) columns. In 1994, the ASCE Task Committee on Design Criteria for Composite Structures in Steel and Concrete issued guidelines for the Design of Joints between Steel Beams and Reinforced Concrete Columns in 1994 (ASCE 1994). Based on research at the time, it was recommended to limit the use of Composite RCS systems to regions of low seismicity. Since then, further research has been performed which has demonstrated that Composite RCS systems can be designed to have reliable ductile performance, making them an attractive design alternative for high seismic areas. Based on this research, a draft Pre-Standard for the Design of Moment Connections between Steel Beams and Concrete Columns (ASCE 2015 draft) has been prepared as an update to the 1994 ASCE connection design guidelines. This draft is utilized for the design studies presented herein.

Accurate seismo-acoustic source location is one of the fundamental aspects of nuclear explosion monitoring. Critical to improved location is the compilation of ground truth data sets for which origin time and location are accurately known. Substantial effort by the National Laboratories and other seismic monitoring groups have been undertaken to acquire and develop ground truth catalogs that form the basis of location efforts (e.g. Sweeney, 1998; Bergmann et al., 2009; Waldhauser and Richards, 2004). In particular, more GT1 (Ground Truth 1 km) events are required to improve three-dimensional velocity models that are currently under development. Mine seismicity can form the basis of accurate ground truth datasets. Although the location of mining explosions can often be accurately determined using array methods (e.g. Harris, 1991) and from overhead observations (e.g. MacCarthy et al., 2008), accurate origin time estimation can be difficult. Occasionally, mine operators will share shot time, location, explosion size and even shot configuration, but this is rarely done, especially in foreign countries. Additionally, shot times provided by mine operators are often inaccurate. An inexpensive, ground truth event detector that could be mailed to a contact, placed in close proximity (< 5 km) to mining regions or earthquake aftershock regions that automatically transmits back ground-truth parameters, would greatly aid in development of ground truth datasets that could be used to improve nuclear explosion monitoring capabilities. We are developing an inexpensive, compact, lightweight smart sensor unit (or units) that could be used in the development of ground truth datasets for the purpose of improving nuclear explosion monitoring capabilities. The units must be easy to deploy, be able to operate autonomously for a significant period of time (> 6 months) and inexpensive enough to be discarded after useful operations have expired (although this may not be part of our business plan). Key parameters to be automatically determined are event origin time (within 0.1 sec), location (within 1 km) and size (within 0.3 magnitude units) without any human intervention. The key parameter ground truth information from explosions greater than magnitude 2.5 will be transmitted to a recording and transmitting site. Because we have identified a limited bandwidth, inexpensive two-way satellite communication (ORBCOMM), we have devised the concept of an accompanying Ground-Truth Processing Center that would enable calibration and ground-truth accuracy to improve over the duration of a deployment.

Using a novel device that simulates earthquakes in a laboratory setting, a Los Alamos researcher has found that seismic waves-the sounds radiated from earthquakes-can induce earthquake aftershocks, often long after a quake has subsided. The research provides insight into how earthquakes may be triggered and how they recur. Los Alamos researcher Paul Johnson and colleague Chris Marone at Penn State have discovered how wave energy can be stored in certain types of granular materials-like the type found along certain fault lines across the globe-and how this stored energy can suddenly be released as an earthquake when hit by relatively small seismic waves far beyond the traditional “aftershock zone” of a main quake. Perhaps most surprising, researchers have found that the release of energy can occur minutes, hours, or even days after the sound waves pass; the cause of the delay remains a tantalizing mystery.

17. Film on the faultline [2015]
- Book
- vi, 292 pages : illustrations ; 23 cm
Film has always played a crucial role in the imagination of disaster. Earthquakes, especially, shift not only the ground beneath our feet but also herald a new way of thinking or being in the world. Following recent seismic events in countries as dissimilar as Chile and Haiti, Japan and New Zealand, national films have emerged that challenge ingrained political, economic, ethical, and ontological categories of modernity. Film on the Faultline explores the fractious relationship between cinema and seismic experience and addresses the important role that cinema can play in the wake of such events as forms of popular memory and personal testimony.

20. Ground motion simulations: validation and application for civil engineering problems [2015] Online
Engineers use earthquake ground motions for a variety of reasons, including seismic hazard assessment, calibration of ground motion prediction equations (GMPEs), and input to nonlinear response history analysis. These analyses require a significant number of ground motions and for some scenarios, such as earthquakes with large magnitudes and short distances, it may be difficult to obtain a sufficient number of
ground motion recordings. When sufficient recordings do not exist, engineers modify
available recordings using scaling or spectrum matching, or they use ground motion
simulations.
Ground motion simulations have existed for decades, but recent advances in simulation
methods due to improved source characterization and wave propagation, coupled
with increased computing power, have increased potential benefits for engineers.
But before simulations can be used in engineering applications, simulations must be
accessible and consistent with natural observations. This dissertation contributes to
the latter issue, and it investigates the application of simulations to specific engineering
problems.
The Southern California Earthquake Center (SCEC) Broadband Platform (BBP)
is an open-source software distribution that enables third-party users to simulate
ground motions using research code contributed by model developers. Because the
BBP allows users to compute their own simulations with little knowledge of the underlying
implementation and it ensures that all calculations are reproducible, it is
extremely valuable for simulation validation and engineering applications. In this dissertation, the BBP is evaluated as a simulation generation tool from an engineering
perspective. Ground motions are simulated to study parameters of engineering
interest, such as high-frequency variability, near-fault ground motions, and local
site response. Though some parameters need further development, such as site response
(which is currently implemented using simple empirical amplification), the
BBP proves to be an e↵ective tool for facilitating these types of engineering studies.
This dissertation proposes a simulation validation framework based on simple and
robust proxies for the response of more complicated structures. We compile a list of
proxies with robust empirical models that are insensitive to changes in earthquake scenario
and do not rely on extrapolation for rarely observed events. Because predictions
of these proxies are reliable under a variety of earthquake events, we can confidently
compare them with simulations. The proposed proxies include correlation of " across
periods, ratio of maximum to median response across horizontal orientations, and
ratio of inelastic to elastic displacement. The validation framework is applied to example
simulations and successfully exposes some parameters that need work, such as
variability and correlation of spectral acceleration.
Finally, this dissertation investigates the application of simulations to response
history analysis and fling-step characterization. A 3D nonlinear structural model
is analyzed using recordings and simulations with similar elastic response spectra.
The structural performance and resulting design decisions are similar, indicating that
simulations are e↵ective for response history analysis subject to certain conditions. To
investigate fling-step, we extract fling pulses from a large set of simulations. Extracted
fling properties such as amplitude and period are then compared to specially-processed
recordings and relevant empirical models for surface displacement and pulse period.
Reasonably good agreement is found between simulations, recordings, and empirical
models.
In general, ground motion simulations are found to be an e↵ective alternative
or supplement to recordings in several engineering applications. Because simulation
methods are still developing, this work is not intended as an evaluation of existing
methods, but rather as a development of procedures that can be used in ongoing
work.
