Finite Element Analysis of Seismic Responses of a Large-Cantilever Stadium Structure

Abstract:

In this paper, based on the Midas/gen platform, a three-dimensional finite element model (FEM) for a transfinite stadium with a large-span and large-cantilever roof , located in Shenyang, was used to study its potential responses to seismic activities. In the numerical analysis, an earthquake spectrum stipulated by the Chinese Seismic Code (GB50011-2010) was adopted to calculate the bidirectional horizontal displacements by the Complete Quadratic Combination (CQC) method on the basis of the response spectrum analysis. The computational results indicate that the maximum displacements in both of the two horizontal directions locate at the top of this structure, i.e. the transfinite part of the roof.
