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.

The structural engineering community has been making great strides in recent years to develop performance-based earthquake engineering methodologies for both new and existing construction. For structural control to gain viability in the earthquake engineering community, understanding the role of controllers within the context of performance-based engineering is of primary importance. Design of a structure/controller system should involve a thorough understanding of how various types of controllers enhance structural performance, such that the most effective type of controller is selected for the given structure and seismic hazard.
The goal of this research is to evaluate the role of structural control technology in enhancing the overall structural performance under seismic excitations. This study focuses on steel moment resisting frames and three types of possible controllers: (1) friction pendulum base isolation system, FPS (passive); (2) linear viscous brace dampers, VS (passive); (3) and active tendon braces, ATB.
