双向单排配筋混凝土剪力墙适用于多层住宅结构,为将其抗震性能与砖砌体结构进行比较,研究低配筋率、水平分布钢筋端部锚固形式、不同边缘构造对高剪力墙抗震性能的影响,进行了4个剪跨比为2.0的高剪力墙低周反复荷载试验研究,其中3个为不同设计参数的混凝土剪力墙,1个为约束配筋页岩砖砌体剪力墙。分析比较了各剪力墙的滞回特性、承载力、延性、刚度及其退化过程、耗能能力及破坏特征。在试验研究基础上,给出了其承载力简化力学计算模型与公式,计算结果与试验结果吻合较好。研究表明,双向单排配筋混凝土高剪力墙的抗震性能优于砖砌体墙,满足多层住宅结构抗震设计要求。
Two-way single-row reinforced concrete shear walls are suitable for multi-story residential structures. In order to compare their seismic performance with brickwork structure, the research on low-reinforcement ratio and horizontal distribution reinforced concrete anchorage forms with different edge structures on high-shear Wall seismic performance, four low shear cyclic loading tests of high shear walls with shear-span ratio of 2.0 were carried out, of which three were concrete shear walls with different design parameters and one was restrained reinforcement shale brick Body shear wall. The hysteretic characteristics, bearing capacity, ductility, stiffness and degradation process, energy dissipation capacity and failure characteristics of each shear wall are analyzed and compared. Based on the experimental study, the simplified mechanics calculation model and formula of its bearing capacity are given. The calculated results are in good agreement with the experimental results. The research shows that the seismic performance of double-direction single-row reinforced concrete high-shear wall is better than that of brick masonry wall to meet the seismic design requirements of multi-story residential buildings.
