Shanghai Pudong Football Stadium is composed of three parts:the first-floor basement structure,the ground stand steel structure,and the large-span roof steel structure.The ground stand structure adopts the steel frame+buckling restraint brace system,and the roof adopts the spoke tensioning system.The roof and substructure were analyzed separately,and the interaction between the upper and lower structures cannot be reflected.To design the overall structure more reliably and reasonably,the overall model analysis was adopted as an important and necessary supplement to the single model analysis.The overall model analysis mainly includes the elastic analysis under frequent earthquakes and fortification earthquakes,the elastic-plastic time history analysis under rare earthquakes,and the stress analysis of super-long concrete structures.The results show that there are limitations of monomer analysis,but the overall model of football field structure is safe.
