装配式薄壁双面叠合剪力墙抗震性能试验研究
Experimental study on seismic performance of prefabricated thin-walled double-superimposed shear walls
摘要
Abstract
To address the problems of poor pouring quality and weak bonding at the interface of double-superimposed shear walls,this paper investigates the seismic performance of a thin-walled double-superimposed shear wall structure.One cast-in-place shear wall specimen(SW)and one thin-walled double-superimposed shear wall(DW)were designed and manufactured for low-cycle reversed loading tests.The failure modes,hysteretic behavior,energy dissipation capacity,ductility,and stiffness degradation of the two specimens were compared and analyzed.The results show that both specimens experienced flexural failure.In specimen DW,the semi-embedded longitudinal reinforcement of the concealed column effectively connected with the reinforcement and work together,which verifies the feasibility of the structural design.Compared with specimen SW,specimen DW had a higher bearing capacity and reduced ductility.Its stiffness degradation showed the characteristic of"high initial stiffness-fast degradation rate".The energy dissipation capacity of the two specimens was similar.The double-superimposed wall demonstrated performance approximately equivalent to cast-in-place,indicating it can meet the engineering requirements in seismic regions.关键词
