摘要
通过对有翼墙和无翼墙的两组共6个对称短肢墙试体的低周反复荷载试验,研究了不同肢厚比、连梁刚度等因素对试体破坏形态、骨架曲线、滞回特性及构件延性的影响,并对两组试体试验结果进行了对比分析,结果表明:肢厚比为6.5左右的短肢墙结构受力性能较好,同时具有一定的能量储备,材料性能发挥较为充分,可以在实际工程中推广使用。
Horizontal cyclic loading experiments are carried out on six specimens, which are divided into two groups, with or without flanged-wall. The influence of different flange-thickness ratio and beam rigidity on the failure modes, skeleton curves, hysteretic response and ductility of six specimens is studied, and the results in the two groups are compared. It is found that the structures whose flange thickness ratio is 6.5 has the best comprehensive structural behavior and is able to work efficiently under cyclic loadings with adequate reliability and economic benefits.
