Abstract: Anyang Sports Center Stadium is a 40000-seat Grade-B stadium,with concrete frame stands and cantileveredtruss canopies. Combining with the requirements of relevant codes,the problems related to complex structural design wereanalyzed from the aspects of structural system,conceptual design,and seismic performance design. Various structural finiteelement calculation programs were used to carry out elastic and elasto-plastic analysis of the roof and the whole structure.The finite element analysis was carried out on the cast steel joints of the bifurcated column supports,and the super-longconcrete stands were reasonably treated to release the temperature stress. Calculations show that by rationally arranging thestructural system and taking appropriate structural measures,the architectural form and function can be realized and theseismic performance requirements of the structure can be met.
