摘要
为了研究由倒锥台型空间预应力混凝土结构看台及安装8片巨型叶片的可开启式钢屋盖组成的上海旗忠网球中心结构体系的施工过程,应用子结构法对上海旗忠网球中心预应力混凝土看台结构施工全过程进行了有限元分析,并进行了施工监测。分析与监测结果表明:上海旗忠网球中心施工质量良好,满足设计要求;应用子结构法明显减少了数据输入、总刚度矩阵阶数以及系统方程求解的工作量,可以实现大型空间结构的施工全过程模拟。
To research construction process of the structure system of Shanghai Qizhong Tennis Center which was characterized by its prestressed concrete structure stand supported by an operable steel roof and 8 mega-blades, the substructure finite element method was used for fullrange analysis of the construction whole process of Shanghai Qizhong Tennis Center, which was also monitored. The results of analysis and monitoring show that the construction quality of Shanghai Qizhong Tennis Center is good, and can satisfy the design requirements. The substructure method which can decrease the data input, the rank of lotal stiffness matrix and the solution work load of system equations significantly, can allow for construction whole process simulation of large-scale spatial structures.
