钢框架内填混凝土墙结构体系有限元分析
Finite element analysis for concrete infilled steel frame
【摘要】 对钢框架—内填混凝土墙结构体系进行了非线性有限元分析,得到了该体系在单向荷载作用下的变形及应力分布状况。为了简化计算,采用对角单压杆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以及纯钢框架模型结果进行比较,得出了一些结论。
【Abstract】 Non-linear finite element analysis for steel frame with concrete infill wall is performed in this paper.The deformation and distribution of stress under mono-loading are achieved.For the purpose of simplified calculation the model of diagonal compress strut is introduced to simulate the properties of infilled concrete wall.The results are achieved through comparing the result of the solid model,diagonal compress strut model and bare steel frame.
