摘要
通过对一榀半刚接钢框架内填RC墙(SRCW)结构模型的低周反复荷载试验,研究了SRCW结构的滞回性能、变形能力、刚度关系以及破坏模式。在此基础上,采用ANSYS软件对其进行了非线性分析,得到了该结构在单调荷载作用下的变形、刚度退化、应力分布及传力机理,分析结果同试验吻合较好。同时对SRCW结构的极限承载力影响因素进行了分析,得出的结论可供进一步研究和工程设计参考。
The experimental study on the composite steel frame-reinforced concrete infill wall strucure under low frequency cyclic reversed lateral loads has been corried out. The hysteretic behavior ,stiffness ,ductility,and failure models are analyzed. Based on the experimental achievments above,the nonlinear finite element computations and ultimate load of the model are obtained. The computing results favorably,coincide with the ones derived from the experiment. After main influential factors are taking into consideration and some results are btained.
