Abstract:In this paper, the differential hysteretic restoring force model is used to simulating the characteristic of restoring force of isolation bearings. The torsional seismic response of one-story asymmetric structure is calculated, the influences of eccentricity of the isolation system and the supper-structure on torsional response of the structure are investigated. It is proved that the torsional response of the structure could be greatly reduced by means of base isolation techniques.
Keywords:differential hysteretic restoring force model  base isolation  torsional seismic response
