摘　　要： 运用非线性有限元,对纯钢框架梁柱节点和钢梁-混凝土剪力墙的顶底角钢半刚性节点的滞回性能进行研究,分析对比两者的滞回性能区别。研究表明:顶底角钢半刚性节点在循环荷载下具有较好的延性和滞回性能;角钢厚度对节点的滞回性能影响明显;钢梁-混凝土剪力墙半刚性节点的耗能能力和滞回性能比纯钢框架梁柱节点的性能有明显提高。 With the nonlinear finite element methods, some research on hysteresis behavior of top-seat-angle semi-rigid connection joints for steel frame and steel beams-reinforced concrete shear walls were analyzed,and both of the hysteresis behavior were contrasted. Results show that the top-seat-angle semi-rigid connection joints have good ductility and hysteresis behavior;the thickness of angle steel affects the hysteresis behavior of joint obviously;the energy dissipation and hysteresis behavior of steel beams-reinforced concrete shear wall semirigid connection joints are better than steel frame beam-column joints.
