摘要 钢框架—内嵌冷弯薄壁型钢复合墙体(PF-CFSF)结构体系可适用于多、高层建筑结构。采用SAP2000有限元分析法针对PF-CFSF结构在水平低周往复荷载下的抗剪滞回性能进行分析,结果表明采用SAP2000有限元法能够较精确的模拟PF-CFSF结构的滞回性能,PF-CFSF结构由于钢框架的参与相对于冷弯薄壁型钢复合墙体耗能能力加强;随着水平位移级的增加,钢框架分担的剪力和耗能能力均相应增大。同时给出了PF-CFSF结构协同工作的抗侧承载力计算简化公式,可用于PF-CFSF结构体系抗震设计。 Steel frame in-filled with cold-formed thin-walled steel framed wall( PF-CFSF) structural system can be used in multi-story and high-rise building. The object of this paper is to study the resistant lateral hysteresis behavior and energy dissipation of PF-CFSF under the low cyclic repeated horizontal load using SAP2000 finite element method. The research results show that SAP2000 finite element can accurately model the lateral hysteresis behavior of PF-CFSF. The energy dissipation of PF-CFSF structure increases compared to that of cold-formed thin-walled steel framed wall because of the participation of steel frame. The shear force and energy dissipation undertaken by steel frame for PF-CFSF structural system will increase with the increase of lateral displacement. The calculation method of the lateral load-carrying capacity of PF-CFSF structural system is put forward which can be applied to seismic design of the PF-CFSF structural system in multi-story and high-rise building.
