摘　　要：对6个1 2缩尺的一字形截面短肢剪力墙构件进行了低周反复荷载下的抗震性能试验研究,墙肢截面高厚比分别为5.0、6.5、8.0,按普通与墙板中加设暗支撑两种情况进行设计。研究了带暗支撑一字形截面短肢剪力墙的承载力、刚度、延性、耗能、滞回特性等,并提出了抗震设计建议。In this paper, firstly, systemic seismic performance static experimental research on I-shaped short pier shear wall models is presented. With three wall width-depth ratios(5.0, 6.5and 8.0), the specimens with the 1/2 scale have been designed in two ways, with and without concealed bracing. Secondly, seismic performance of I-shaped short pier shear walls, including bearing capacity, stiffness, ductility, energy dissipation and hysteresis property, is discussed. Thirdly, some seismic advice on design is provided.
