The nonlinear FEM analysis of precast concrete frame structures was carried out by commercial software ANSYS. The nonlinear behavior of materials, assembly of precast concrete component, prestressing, and boundary conditions were taken into account in the FEM model. Test of the precast concrete frame structures of Shanghai Qizhong Tennis was conducted under monotonic static loads to verify the above model, and the calculations were consistent with the test results.%采用商用软件ANSYS,建立了考虑材料非线性、预制混凝土结构拼缝、预应力以及边界条件等的非线性有限元模型,对预制混凝土框架进行了非线性全过程分析.基于上海旗忠网球中心预制混凝土框架结构模型的单调静力试验,对上述有限元模型进行了验证,有限元计算值与试验结果吻合良好.
