摘　　要：为推广冷弯薄壁型钢填充复合墙板在高层结构中的应用,进一步了解该冷弯薄壁型钢填充复合墙板作为抗侧力构件应用于高层结构中的抗震性能,将冷弯薄壁型钢填充复合墙板引入半刚性钢框架结构中并研究其抗震性能。基于有限元分析软件SAP2000,采用Pivot恢复力模型对冷弯薄壁型钢填充复合墙板进行简化分析,并推导出墙板P-Δ骨架曲线关系公式;采用转角弹簧单元对矩形钢管柱与H形钢梁单边高强螺栓连接节点进行简化分析;并在此基础上建立半刚性钢框架-冷弯薄壁型钢填充复合墙板结构简化分析模型。在此简化基础上,建立1个10层3跨半刚性空框架和3个以墙板布置方式为参数的半刚性钢框架-冷弯薄壁型钢填充复合墙板结构,利用时程分析方法考察了4类框架结构在8度区不同设防水准下的顶点位移、层间位移角等,获悉结构在不同地震作用下的动力响应。研究结果可为后续该结构的抗震性能分析奠定基础。In order to promote the application of light CFS infilled wall in high-rise buildings and utilize the light CFS infilled wall as a lateral force resistant member,this paper introduces a CFS infilled wall into semi-rigid steel frame structures and studies the seismic performance of a semi rigid steel frame-CFS infilled wall structures.Using SAP2000 finite element analysis software,the Pivot model is used to simplify the CFS infilled walls,and a formula of P-Δ skeleton curve of walls is obtained.Meanwhile,the corner spring element is used to simplify the joint of rectangular steel pipe columns and H-shaped steel beam high-strength blind bolts.Based on the simplified model above,a nonlinear analysis model of semi-rigid steel frame-CFS infilled wall structures is built.Based on the analysis above,a pure ten-story model with three-span semi-rigid frame and three semi-rigid steel frame-CFS infilled wall structures are built.The top displacement and story drift ratio of four kinds of frame structures under different fortification levels in eight degree area are investigated by using time-history analysis method,and the dynamic response of structures under different earthquake actions is obtained.This paper provides a reference for future seismic analysis of this structure.
