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 the three-tie rod equivalent model and the static nonlinear analysis method, the SAP 2000 is used to perform the static pushover analysis on the 3-span steel frame-steel plate shear wall structure. Under the action of lateral load, through the analysis of the bottom shear force-apex displacement, interlayer displacement, structural plasticity development and floor shear distribution of steel frame-steel plate shear wall structure, And the semi-rigid connection of the overall structure of the seismic performance. The results show that when the whole structure is in elastic stage, the horizontal shear force of the steel plate shear wall is 50% of the floor shear force. When the whole structure enters the elastic-plastic state, the steel plate shear wall structure takes 70% ~ 80% of the floor shear Under the action of lateral load, the steel plate shear wall first enters the yielding stage, and then the plastic hinge appears at the end of the frame beam, and the plastic hinge at the end of the frame part of the frame finally meets the requirements of multi-channel seismic defense and has good earthquake resistance performance.
