Abstract: This paper takes the project of Nanjing Youth Olympic Center-Conference Center as the background, and uses MIDAS Gen to establish the three-dimensional nonlinear structure analysis model. Under the guidance of design thought based on the seismic performance and seismic design method based on the displacement, the dynamic elastic-plastic time history analysis of the whole structure of elastic floor, and a weakening elastic floor respectively under a large earthquake was camed out. The structure displacement and plastic hinge distribution show that the overall seisnuc performance of the conference center is good, which satisfies the structure seismic performance objectives of the large earthquake.
Keywords: complex spatial structure; large earthquake; dynanuc elastic-plastic time history analysis
