The main structure of Chongqing Longxing Football Stadium adopts a frame structure with a small number of shear walls, and the roof steel structure adopts a cantilevered plane truss+upper and lower chord stable support+facade single-layer grid structure.
In order to study the difficulties in structural design, SPASCAD-PMSAP, MIDAS Gen (Ver.
2019), and SAP2000 design software were used to analyze the seismic performance of the structure under multiple earthquakes.
SAUSAGE and SAP2000 software were used to analyze the seismic performance of the structure under fortification and rare earthquakes.
ANSYS software was used to analyze the overall stability of the steel roof, and ABAQUS software was used to analyze the stress performance of the nodes.
The results indicate that the structure has good seismic resistance and resistance to continuous collapse, and the structural design is safe, reasonable, and economical.
