［摘要］第七屆世界軍運會主賽場鋼結(jié)構(gòu)屋蓋采用車輻式索承網(wǎng)格結(jié)構(gòu)。采用MIDAS Gen軟件對整個鋼結(jié)構(gòu)屋蓋的施工進行模擬分析，主要包括鋼結(jié)構(gòu)吊裝過程分析和索張拉施工過程分析。通過計算分析可以精確計算出鋼結(jié)構(gòu)構(gòu)件在施工全過程的應(yīng)力大小，以及預(yù)應(yīng)力索在張拉過程中的應(yīng)力大小，從而保證施工過程的安全性和施工監(jiān)測的預(yù)見性。

Abstract:The steel structure roof of the Main Stadium of Seventh World Military Games used car spoke-styled cable supported lattice structure. The construction of the whole steel structure roof was simulated and analyzed by the finite element analysis software MIDAS Gen. The analyses mainly included the analysis of the steel structure hoisting process and the analysis of the tensioning process. Through the calculation and analysis, the stress of the steel structural members could be calculated accurately in the whole process of construction and the stress of the prestressed cable could be calculated during the tensioning process, which could ensure the safety of the construction process and the foresight of construction monitoring．
Keywords:the Main Stadium of Seventh World Military Games; steel structure roof; cable supported lattice structure; construction simulation analysis; cable tension construction
