两边连接开缝钢板剪力墙具有延性好,耗能能力强等优点,同时有效避免了四边连接钢板剪力墙对框架柱产生的附加荷载,避免了与剪力墙相连框架柱的早期破坏。该文对两边连接开缝钢板剪力墙的弹性屈曲性能进行分析,系统考察了缝间小柱高宽比、宽厚比、开缝排数等参数的影响;同时分析了缝间小柱的屈曲性能,给出缝间小柱端部先于钢板整体弹性屈曲时的临界高厚比限值;分析结果表明,开缝钢板剪力墙保持平面内工作且通过缝间小柱端部形成塑性铰承担荷载并耗能时的理想开缝原则为缝间小柱宽厚比b/t<15且高宽比h/b>3.0。
The two sides connected with slit steel shear wall have the advantages of good ductility and strong energy dissipation. At the same time, it can effectively avoid the additional loads on the frame columns by the four-sides connected steel plate shear wall and avoid the early damage of the frame columns connected with the shear walls. In this paper, the elastic buckling performance of the shear wall connected with slit steel slabs on both sides is analyzed. The influence of parameters such as aspect ratio, aspect ratio, The critical height-to-thickness ratio limit at the end of the slotted column before the overall elastic buckling of the steel plate is given. The analysis results show that the slitted steel plate shear wall works in-plane and forms the plastic hinge The ideal slotting principle for loading and energy dissipation is the ratio of width to thickness of bored pillars b / t <15 and aspect ratio h / b> 3.0.
