【摘要】 为了研究单排配筋混凝土剪力墙结构中带有不同边缘构造配筋的墙肢与连梁节点抗震性能,进行了4个墙肢与连梁节点的低周反复荷载试验.在试验研究基础上,分析了其承载力、延性、刚度、滞回特性、耗能能力、破坏特征等,并建立了单排配筋剪力墙连梁承载力计算模型,计算所得承载力与试验结果符合较好.研究结果表明,单排配筋混凝土剪力墙节点经过合理的配筋及构造措施能满足多层住宅结构抗震设计要求.更多还原

【Abstract】 In order to study on the seismic performance of joint of coupling wall-column and coupling wall-beam in the RC shear wall with bi-directional single row of steel bars,a low-frequency quasi-static cyclic loading test of four joint models with different details of seismic design is carried out. The load-carrying capacity,ductility, stiffness,energy dissipation and failure phenomena of each specimen are analyzed and calculative formulas of the load-carrying capacity is established,and the calculating results agree well with the experimental results. Experiments indicate that the joint with reasonal detailing reinforcement is able to satisfy the requirements of seismic design for multistory residence building.更多还原
