ABSTRACT
In recent years, to solve the problem of serious damage caused to the traditional building structures that are difficult to repair after earthquakes, the seismic mitigation and isolation technology have been continuously developed. To reduce the seismic response of the structure, a new type of layered suspension structure system is proposed, and the finite element software OpenSees is used to build a nonlinear model of this structure for numerical simulation; at the same time, material nonlinearity and geometric nonlinearity are also considered. The response of the layered suspension structure and the ordinary frame structure under different seismic waves is compared and analyzed, and the calculation results show that the seismic performance of the layered suspension structure is better than that of the ordinary frame structure.
