【摘要】 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。更多还原

【Abstract】 Three different kinds of mechanical model are built by changing the cross-sectional area of the frame columns.Based on nonlinear finite element theory,a system which is composed of shell and reinforced concrete frame structure is analyzed by using finite element program ANSYS.In the analysis,the K8 grid shell affected by the changes of the frame structure is analyzed systematically under the earthquake loading.更多还原
