双向单排配筋高剪力墙抗震试验及计算分析
|
摘要
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。
The RC shear wall with bi-directional single layer of steel bars is applicable for multistory residence building.In order to study the effects of low steel ratio,boundary element and anchorage type of horizontal reinforcing bars on seismic performance of high-rise RC shear walls with bi-directional single layer of steel bars,as well as compare its seismic performance with masonry shear wall,quasi-static cyclic loading tests on four 2.0 shear-span ratio high-rise shear wall specimens were carried out.Four high-rise shear walls included three RC shear walls with different design parameters and one masonry shear wall made of confined shale bricks.The load-carrying capacity,ductility,stiffness variation,hysteretic behavior,energy dissipation and failure phenomena of each shear wall with different design parameters were compared.Based on the experimental study,the mechanical model and equations for calculating load-carrying capacity were proposed.The calculating results of the load-carrying capacity agreed well with the experimental results.The tests show that the seismic performance of high-rise RC shear walls with bi-directional single layer of steel bars surpasses the masonry shear wall,demonstrating the suitability of such shear wall for use in seismic multistory buildings in seismic regions.
