Numerical Simulation Analysis of Collapse Process of Isolated Structure in Strong Earthquakes

Abstract

In this paper, the Abaqus model of an 8 layer isolation structure is established, and the connector element provided in the software is used to simulate the stiffness multilinearity in the horizontal and vertical direction of the isolation bearing. In the numerical analysis, six kinds of working conditions are set up to compare the vertical displacement, the peak acceleration and the interlayer displacement etc, and the effect of bearing failure on the superstructure is obtained.
