为了研究全预制装配式混凝土柱-钢梁(RCS)混合结构的摩擦拼接耗能节点对框架结构整体抗震性能的影响,结合试验的破坏特征,建立了摩擦拼接耗能节点的弯矩-转角关系模型,利用Link单元模拟实际的摩擦拼接耗能节点。通过与试验结果对比,验证了该单元的合理性。在此基础上,以某5层框架为例,分别建立有摩擦拼接耗能节点与无摩擦拼接耗能节点的框架结构模型,进行了模态分析和Pushover非线性分析。研究结果表明:连接的刚度会影响结构的低阶自振周期,但是对高阶模态的影响很小;采用摩擦拼接耗能节点能够有效减小全预制装配式RCS混合结构的底部受力,且框架表现出较好的延性;结构的层间位移角都符合抗震规范的要求。 In order to study the effect of the friction-spliced ​​energy-dissipating nodes of the prefabricated prestressed concrete-filled steel column (RCS) hybrid structure on the overall seismic performance of the frame structure and the failure characteristics of the test, the moment- Model, the Link unit is used to simulate the actual friction splice nodes. By comparing with the test results, the rationality of the unit is verified. On the basis of this, taking a 5-story frame as an example, the frame structure model of frictional energy-consuming nodes and non-frictional energy-consuming nodes is established respectively, and modal analysis and Pushover nonlinear analysis are carried out. The results show that the stiffness of the connection affects the low-order natural vibration period of the structure, but has little effect on the high-order mode. Frictionally splicing energy dissipation nodes can effectively reduce the bottom force of the prefabricated RCS hybrid structure, Showing good ductility; the structure of the layer displacement angle are in line with seismic requirements.
