摘要
基于三拉杆等效模型和静力非线性分析方法,利用SAP 2000对3跨钢框架-钢板剪力墙结构进行静力推覆分析。在侧向荷载作用下,通过对钢框架-钢板剪力墙结构的底部剪力-顶点位移关系、层间位移、结构塑性发展、楼层剪力分配等指标的分析,研究梁柱节点采用刚性连接和半刚性连接时整体结构的抗震性能。结果表明：在整体结构处于弹性阶段时,钢板剪力墙承担的水平剪力为楼层剪力的50%,整体结构进入弹塑性状态时,钢板剪力墙结构承担70%~80%的楼层剪力;在侧向荷载作用下,钢板剪力墙最先进入屈服阶段,而后是框架梁端部出现塑性铰,最后部分框架柱端形成塑性铰,符合多道抗震防线的要求,具有良好的抗震性能。
Based on equivalent three-strip model and nonlinear static analysis procedure, the static pushover analysis of the three-span steel frame-steel plate shear walls was made by using SAP 2000. Under lateral loads, the load- displacement curve, storey drift, plastic development and the internal shear force distribution of the said structure were analyzed. The seismic behavior of the steel shear wall systems with rigid connection and semi-rigid connection was researched. The results indicate that the steel shear wail hears approximately 50~/0 floor shear when the structure is in the elastic stage, and the shear wall bears 70% - 80% floor shear when the structure is in the elastic-plastic state. The steel plate shear wall first yields, and then the plastic hinges appear at steel beam end, finally some plastic hinges form at a few steel column end. So the steel shear wall systems have multiple seismic-proof line, showing excellent seismic behavior.
