摘　　要：对2010年上海世博会主题馆整体结构进行了ETABS和ANSYS建模分析。对屋盖结构进行了结构整体模型和屋盖单独模型的极限承载力分析比较,表明整体模型能充分真实的反映结构的全过程状态,屋盖单独模型则可用于进行结构初步设计判断;将结构ANSYS模型与ETABS模型二者动力特性对比,结果表明对结构简化建模的合理性及建模的正确性;通过对整体结构的静力弹塑性分析表明结构具有较好的水平抗侧力刚度,结构满足三水准的抗震设防目标。The thesis carries out ETABS and ANSYS modeling analysis on the integral model of the theme pavilion of 2010 Shanghai World Ex- po, compares the ultimate bearing capacity of integral roof structure model and single roof structure model, and shows that integral model can ae- tuaUy reflect the overall process state, and single roof model can be used to identify preliminary structure design. The dynamic performance com- parison of ANSYS model and ETABS model shews the rationality and correctness of modeling simplifieation. The static plastic analysis of the inte- gral structure shows the structure has better horizontal lateral resistance force rigidity, and the structure meets three-standard seisrnie resisting target.
