摘要
对4个1/2缩尺的长肢一字形截面柱构件进行了低周反复荷载下的抗震性能试验研究,构件截面高厚比分别为4.0、4.5与5.0,分别按柱子配筋与按剪力墙配筋两种配筋方式进行设计。通过试验分析了长肢一字形截面柱的承载力、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, static experimental research on systemic seismic performance of long pier Ⅰ- shaped column models is presented. With three wall width-depth ratios（4.0, 4.5and 5.0） , the 4 specimens with the 1/2 scale have been designed in two ways, in one way the column is reinforced by steels, and the other way the short pier shear wall is reinforced by steels. Secondly, seismic performance of the long pier Ⅰ- shaped columns is discussed, which includes bearing capacity, stiffness, ductility, energy dissipation and hysteresis property. Thirdly, some seismic advice on design is provided.
