Isolation Performance Analysis of Concrete-Filled Steel Tubular Composite Structure Based on the Lead Rubber Bearing

Abstract

With a 6 layer of concrete-filled steel tubular column-steel beam frame structure as the object of study,established finite element model of the structure is based on Sap2000,the traditional structure model and the isolation structure model were compared.The research results show that the dynamic characteristics of structure storey drifts and acceleration with Lead Rubber Bearing are smaller than the model without Lead rubber bearing under different earthquake intensities. The isolation effect is considered obvious.
