钢框架内填开洞RC剪力墙结构的有限元分析及简化计算模型的探讨

Construction and Performance Analysis of the Composite Steel Frame-precast Reinforced Concrete Infill Wall

对钢框架—内填中间开洞混凝土墙结构体系进行了弹性有限元分析,得到了该体系在单向荷载作用下的变形及应力分布状况。为了在实际工程设计中进行简化计算,采用交叉钢支撑模型模拟内填墙的受力特性,并将计算结果同有限元实体模型进行比较,得出了一些结论和建议。

Elastic finite element analysis for steel frame with concrete infilled wall which is with opening is performed in this paper.The deformation and distribution of stress under mono-loading are achieved.For the purpose of simplifying the calculation during project design,the model of cross steel brace is introduced to simulate the properties of the infilled concrete wall.The results are achieved through comparing the results of the models,such as the solid model with whole infilled wall,solid model of walls with opening,model of crossed steel brace,model of steel frame without braces.Some conclusion and suggestion will be given.
