VERIFICATION OF ALL STORY SEISMIC BUILDING RESPONSE ESTIMATION METHOD FROM LIMITED NUMBER OF SENSORS USING LARGE SCALE SHAKING TABLE TEST DATA

Abstract

This paper propose a method to estimate overall building responses during an earthquake using acceleration records from limited seismographs those have input-output relationship. The design model of the building is updated to a model closer to reality by applying Bayes’ theorem, to estimate building responses. The method is applied to seismic response analysis results, which shows extremely precise evaluation ability of the method. To evaluate the accuracy of the method, the method was applied to using large shaking table test where building responses of each layer have been recorded. The response estimation results substantially match the actual observations.
