摘要

双向单排配筋剪力墙结构适用于多层住宅结构。为探讨双向单排配筋剪力墙与连梁节点的抗震性能,进行了4个连梁剪跨比分别为0.60、0.75、1.50、1.75的原型节点试件的低周反复荷载试验,在试验研究的基础上,较系统地分析了节点的承载力、刚度及其退化过程、延性性能、破坏特征等。试验研究表明,双向单排配筋剪力墙与连梁节点的抗震性能可满足多层住宅结构抗震要求。
RC shear wall with bi-directional single row of steel bars is applicable for multistory residence building.In order to analyze the seismic performance of joints of coupling beam and shear wall with bi-directional single row of steel bars,experimental studied on the joints of the coupling beam with different shear-span ratio under a low-frequency quasi-static cyclic loading were carried out,and the shear-span ratios of coupling beams are 0.60、0.75、1.50、1.75.Based upon the experimental studies,load-carrying capacity,stiffness and its degradation,ductility and failure phenomena of each specimen are analyzed systematically.Experiments indicate that the joint with the bi-directional single row of steel bars is able to satisfy requirements of seismic bearing capacity of multistory residence building through rational design.
