摘　　要：通过对1片普通钢筋混凝土现浇剪力墙和1片预制带肋叠合整体式剪力墙的拟静力试验,对两片剪力墙的破坏形态、承载力、变形能力、滞回特性、刚度退化、耗能能力等进行研究分析。结果表明:两片剪力墙均发生弯曲破坏;叠合剪力墙整体性好,其破坏形态、裂缝分布、滞回特性、刚度退化趋势与现浇剪力墙近似;叠合剪力墙的整体刚度大于现浇剪力墙,位移延性及耗能性能与现浇剪力墙相近。Quasi-static experiments on one piece of conventional reinforced concrete（ RC） cast-in-situ shear wall and one piece of prefabricated superimposed ribbed reinforced integral shear wall were conducted. The failure patterns,bearing capacities,hysteretic characteristics, stiffness degradations and energy dissipation capacities of the two shear wall specimens were investigated. The result shows that there are flexural failures in both of the two specimens; superimposed shear wall has well integral properties and its failure pattern,crack distribution,hysteretic characteristic and stiffness degradation potential are similar as those of cast-in-situ shear wall; the integral stiffness of superimposed shear wall is higher than that of cast-in-situ shear wall and the displacement ductility and energy dissipation capacity of superimposed shear wall are close to those of the cast-in-situ shear wall.
