为研究半刚性框架-两边连接防屈曲钢板剪力墙结构的抗震性能,进行了一榀1∶3比例的单跨两层半刚性框架-两边连接防屈曲钢板剪力墙结构的拟静力试验,试验研究了半刚性框架与内填防屈曲低屈服点钢板的相互作用,并获得其承载力、刚度、骨架曲线、耗能性能等指标。试验结果表明:该种结构具有优越的耗能能力,半刚性框架和内填低屈服点钢板协同工作良好;边缘加劲槽钢的设置为内填钢板提供有效锚固,解决了普通两边连接钢板剪力墙有效抗剪面积折减过大的问题;纵横密肋可改善内填钢板的受力状态,内填钢板以密肋间小区格局部屈曲为主,提高结构的刚度及承载力,避免了普通两边连接钢板剪力墙滞回曲线的严重“捏缩”效应。研究结果可供相关结构体系理论分析和工程应用参考。
In order to study the seismic behavior of semi-rigid frame with both sides connected with anti-buckling steel plate shear wall structure, a quasi-static test of single-span two-story semi-rigid frame with both sides connected with anti-buckling steel plate shear wall structure , The interaction between semi-rigid frame and buckling-proof low yield point steel plate is experimentally studied, and the indexes such as bearing capacity, stiffness, skeleton curve and energy dissipation performance are obtained. The results show that this kind of structure has the superior energy-dissipating ability, and the semi-rigid frame cooperates well with the low-yielding point steel plate with internal filling. The setting of the edge stiffened channel steel provides effective anchoring for the inner steel plate and solves the problem of shear stress Wall effective anti-shear area reduction problem is too large; longitudinal and horizontal ribs can improve the stress state of steel plate, filled steel plate to the intercalary cells in the Department of local buckling-based structure to improve the structural rigidity and bearing capacity to avoid the ordinary Serious “pinch-in” effect of the hysteresis curve connecting the steel sheet shear walls on both sides. The research results are available for theoretical analysis and engineering application of related structural systems.
