为研究半刚性框架-槽钢十字形约束钢板剪力墙结构的抗震性能,通过一榀1∶3比例单跨3层半刚性框架-槽钢十字形约束钢板剪力墙的拟静力试验,研究半刚性框架与槽钢约束墙体的相互影响,分析结构的承载力、刚度、耗能和节点转动能力等。试验结果表明:该结构具有良好的耗能能力,半刚性框架和墙板协同工作良好,墙板的设置显著降低梁柱节点的延性要求,避免梁柱刚性连接在强震作用下的脆性破坏;槽钢构件的设置可改善钢板的受力性能,提高墙体的承载力和刚度,有效减少滞回曲线的“捏缩”现象,降低薄板墙的噪音及震颤,内填板以小区格内的局部屈曲为主,试件面内呈弯剪破坏模式。
In order to study the seismic behavior of the semi-rigid frame-cross-section steel plate shear wall structure with channel cross-section, the pseudo-static test of the cross-shaped three-layer semi- The interaction between the semi-rigid frame and the channel-confined walls is studied, and the bearing capacity, stiffness, energy consumption and node rotation capacity of the structure are analyzed. The experimental results show that the structure has good energy dissipation capacity, and the semi-rigid frame and the wall panels work well together. The installation of the wall panels significantly reduces the ductility requirements of the beam-column joints and avoids the brittle failure of the rigid connections of the beam columns under strong earthquakes. The arrangement of the channel members can improve the stress performance of the steel plate, increase the bearing capacity and rigidity of the wall, effectively reduce the “pinch-in” phenomenon of the hysteresis curve, reduce the noise and tremor of the thin plate wall, Local buckling is the main part of the specimen.
