通过调整框架柱的横截面积建立了三种不同的力学模型。依据非线性有限元理论,利用ANSYS有限元分析程序,把钢筋混凝土支承框架和单层网壳结构体系作为一个整体结构体系进行分析。通过分析,系统地研究了地震荷载作用下支承框架的变化对网壳结构力学性能的影响。
Three different mechanical models were established by adjusting the cross-sectional area of the frame column. Based on the nonlinear finite element theory and ANSYS finite element analysis program, the reinforced concrete support frame and the single-layer reticulated shell structure system are analyzed as a whole structural system. Through the analysis, the influence of the change of the supporting frame on the mechanical properties of the reticulated shell under the earthquake load is studied systematically.
