Abstract:The canopy of Zhengzhou Olympic Sports Center Stadium adopts the spoke-typed cable-supported grid structure, and it belongs to the new spatial steel structural system in China. MIDAS Gen and ANSYS software were used to analyze the static performance of the structural system, and on this basis, the structural system was optimized through structural parameter analysis. The response spectrum and time-history analysis methods were used to carry out the research on the seismic performance of the structure, and the wind tunnel test research and the wind-induced response analysis were carried out; on the basis of the linear and bi-nonlinear stability analysis and the anti-progressive collapse analysis of the structure, further carrying out the whole process of construction simulation analysis. The research results show that the spoke-typed cable-supported grid structure has good static and dynamic performance, and has great advantages in structural span, cantilever length, and lower headroom height, so it is suitable for application and promotion in large-span and large-cantilever buildings.

Keywords:Zhengzhou Olympic Sports Center Stadium; spoke-typed cable-supported grid structure; parameter analysis; pop response; time-history analysis; construction simulation analysis
