摘要:
为了使装配式剪力墙在水平拼缝处得到可靠连接,引入扣接封闭箍筋,分别对1个装配式剪力墙试件和1个现浇剪力墙试件进行低周反复荷载加载试验,并分析两试件的强度、刚度、位移延性及耗能能力等抗震性能指标。结果表明:扣接封闭箍筋可以限制约束区混凝土的横向变形,对波纹管浆锚搭接钢筋形成较好约束,并改善纵筋间的间接搭接性能; 与现浇剪力墙试件相比,装配式剪力墙试件的延性和耗能能力相当,但承载能力有较大提高。
Abstract:
As an important form of building structures in China,it is significant to research industrialization of shear wall structures.For a reliable connection in horizontal connections of precast concrete shear wall,overlapping closed stirrup was picked,a fabricated and a cast-in-place shear wall specimen were tested under low cyclic loading.The strength,stiffness,ductility and energy dissipation of the two specimens were analyzed.The test results showed that overlapping closed stirrup can restrict lateral deformation of concrete in restrained area,restrain grouting connection in bellows for steel bar anchorage and improve lap performance of longitudinal bar; compared with cast-in-place shear wall specimen,the ductility and energy dissipation of fabricated shear wall specimen was the same,but the force increased.
