STUDY ON TORSIONAL RESPONSE OF SEISMICALLY ISOLATED BUILDING ON SOIL WITH INCLINED BEDROCK USING STRONG MOTION RECORDS

Abstract

This report examined torsional response of a seismically isolated building on inclined bedrock using strong motion records. Ground motions increases the amplitude and produces time lag to propagate in according to a layer thickness of the surface ground. We also evaluate the torsional response using ratio of it. In result, torsional response of floor on seismically isolated layer is reduced to half by effect of it in comparison with basement.
