Strong Earthquake Motion Estimates for the UCSB Campus, and Related Response of the Engineering I Building

摘要

This report was prepared under the UC/CLC Campus Earthquake Program. The project was initiated as part of the Campus-Laboratory Collaboration (CLC) Program created by the University of California Office of the President (UCOP). The UC/CLC Campus Earthquake Program (CEP) started in March 1996, and has involved a partnership between seven campuses of the University of California - Berkeley, Davis, Los Angeles, Riverside, San Diego, Santa Barbara, Santa Cruz - and the Lawrence Livermore National Laboratory (LLNL). It is designed to estimate the effects of large earthquakes on three of those campuses. Each campus has selected a critical site to demonstrate the methods and procedures used by the CEP. The following sites have been selected: the Rivera Library at U.C. Riverside, the Thornton Hospital at U.C. San Diego, and the Engineering I building at U.C. Santa Barbara. The project focuses on the estimation of strong ground motions at each critical site. These estimates are obtained by using an integrated geological, seismological, geophysical, and geotechnical approach, bringing together the unique capabilities of the campus and laboratory personnel. This project is also designed to maximize student participation. Many of the site-specific results are also applicable to risk evaluation of other sites on the respective campuses.
