高强混凝土-型钢组合剪力墙抗震性能试验
|
摘要
通过对3个1/3缩尺的高强混凝土剪力墙模型的抗震性能试验,探讨了不同组合形式剪力墙的承载力、刚度及退化过程、延性、滞回特性及破坏特征;将试验结果与普通强度混凝土剪力墙的试验结果进行了对比.结果表明:内藏钢框架混凝土剪力墙和内藏斜向支撑钢框架混凝土剪力墙的抗震性能比普通混凝土剪力墙的承载力、后期刚度、延性均比普通强度混凝土剪力墙有明显的提高.计算与试验吻合较好.
Three kinds of 1 /3 scale model of shear walls,including normal high strength concrete shear wall(SW),SW incorporated with steel frame(TSW),and TSW combined with braces of truss constituted by bars(TSW-BT),were tested to evaluate their seismic behaviors.Meanwhile,their characteristics such as bearing capacity,stiffness and attenuation,ductility,hysteretic property and failure phenomena were analyzed and discussed.In addition,comparisons between seismic behaviors of SW,TSW,TSW-BT and normal strength shear wall were carried out.It is shown that the proposed shear walls share good performance,and most of their properties related to seismic behavior are superior to normal strength shear wall.At last,the bearing capacity of this kind shear wall is calculated,which result agrees quite well with the result of the experiment.
