摘要
浦东国际机场T2航站楼主楼钢屋盖为复杂大跨空间结构。采用有限元分析程序ANSYS对航站楼主楼包含下部混凝土框架和上部钢屋盖的整体结构进行了罕遇地震下三向地震波输入的弹塑性时程分析,跟踪了钢屋盖的位移、关键构件应力、内力历程等动力反应,并加以分析比较,考察钢屋盖的弹塑性发展历程。根据分析结果对钢屋盖结构的抗震性能进行了评价,认为钢屋盖结构具有良好的抗震性能。
The roof structure of Shanghai Pudong International Airport T2 is a complex long-span space structure. Elastoplastic time-history analysis for the integral structure of the steel roof structure and its RC substructure subjected to three dimensional earthquakes is carried out with finite element analysis program ANSYS. Dynamic response of the structure such as displacement, stress and internal force of the key structural members is traced, and analyzed by comparison. The process of elasto-plastic development is researched. Based on the analysis, the seismic performance of the roof structure is evaluated, and it is shown that the seismic performance of the roof structure is well.
