[摘要] 设计制作了 6 片一字形短肢剪力墙试件,分为 3 组,每组 2 个试件中,在保持配筋率一致的情况下,一个采
用截面等强度配筋,另一个设置暗柱。对其进行了低周反复荷载试验,研究不同配筋形式下的一字形短肢剪力墙的
抗震性能。基于试验结果对试件的破坏形态、滞回性能、位移延性、耗能能力等方面进行了分析。结果表明设置

暗柱的一字形短肢剪力墙的承载能力、位移延性和耗能能力明显优于没有设置暗柱的,建议对一字形短肢剪力墙
应采用带暗柱的配筋形式。

Abstract :Six models of the rectangular section short pier shear wall (SPW) were designed and divided into three groups. In each
group , under the same reinforcement ratio , one specimen used uniform reinforcement and the other set concealed column. The
models were tested under quasi static , reversed cyclic horizontal loads in order to investigate the seismic performance under
different reinforcement layout pattern. Based on the experimental results , seismic performance of the rectangular section SPW such
as failure pattern , failure mechanism , characteristic loads , ductility and energy dissipation etc. were investigated. The results show
that the seismic performance of the rectangular section SPW with concea
