This series includes technical reports prepared by faculty, students and staff who are associated with the John A. Blume Earthquake Engineering Center at Stanford University. While the primary focus of Blume Center is earthquake engineering, many of the reports in this series encompass broader topics in structural engineering and materials, computational mechanics, geomechanics, structural health monitoring, and engineering life-cycle risk assessment. Each report includes acknowledgments of the specific sponsors for the report and underlying research. In addition to providing research support, the Blume Center provides administrative support for maintaining and disseminating the technical reports.

Empirical methods of characterizing recorded strong ground motion have been confined to primarily peak value summaries. There are particular advantages to peak values, specifically the ease with which they can be defined and used. However this use as a means of summarizing a nonstationary process has often been questioned. This work looks into the basic theoretical and empirical properties of the root mean square and duration as a means of characterizing the strong motion acceleration of earthquakes. This coupled means of summarizing ground motion is investigated as a possible alternative characterization of ground motion intensity for use in seismic hazard analysis.
