[提要]  应用ANSYS软件对广州市新体育馆主场馆钢屋盖结构进行了安装过程的动态跟踪分析。跟踪分析的主要目的是实时了解吊装和拆撑两个阶段钢屋盖内力和变形的变化情况，并根据分析结果复核、优化施工吊装方案和拆撑方案。计算分析为钢屋盖安装提供了理论依据。

Based on the ANSYS finite element nonlinear analysis, this paper presents the continuous changing of deformation and internal force distribution of truss roof structure of Guangzhou New Gymnasium during its erection process. The emphasis is paid on the theoretical investigation to safety behavior of the roof structure from hoisting state into design state after removing temporary pillars. The proposed erection scheme were checked theoretically, and some modifica-tions were made accordingly.
