Over-limit structure design of Chongqing Longxing Football Stadium
The main structure of Chongqing Longxing Football Stadium adopts a frame structure with minor shear walls.The roof steel structure adopts a cantilever plane truss+upper and lower string stable support+single-layer grid structure.In order to study the difficulties of structural design,SPASCAD-PMSA,MIDAS Gen(Ver.2019)and SAP2000 design softwares were used to analyze the seismic performance of the structure under frequent earthquake.SAUSAGE and SAP2000 softwares were used to analyze the seismic performance of the structure under fortification and rare earthquake.ANSYS software was used to analyze the overall stability of the steel roof,and ABAQUS software was used to analyze the mechanical properties of the joints.The results show that the structure has good seismic capacity and progressive collapse resistance,and the structural design is safe,reasonable and economical.
