摘　　要：文章对双腹板顶底角钢连接钢框架进行非线性有限元分析,研究了该种框架的受力及变形特点、结构的延性、刚度等性能,分析了框架节点的受力特点及各部件的应力、应变变化情况,为该种连接钢框架的周期往复荷载试验的进行提供依据;同时对双腹板顶底角钢连接钢框架进行弹性阶段周期往复试验,获得其初始刚度,为后续拟动力试验提供依据。Through the nonlinear finite element analysis of the steel frame with top-seat and double web angles connections, the distortion characteristics and the ductility and rigidity of the steel frame are studied, and the stress distributing character and the variety of stress and strain on the joint parts are also discussed. The experiment on the frame under low reversed cyclic loading is carried out, and the original rigidity of the frame is gained. The results provide a basis for later pseudo-dynamical experiment.
