摘    要:对1片现浇剪力墙和轴压比不同的3片新型钢管混凝土边缘约束叠合剪力墙进行拟静力试验,研究其在往复水平荷载作用下的试验现象、破坏形式和抗震性能,提出钢管混凝土边缘约束叠合剪力墙屈服承载力的计算方法;采用XTRACT有限元分析软件对新型剪力墙峰值承载力进行算例验证,二者结果吻合较好。研究表明:钢管混凝土边缘约束叠合剪力墙的水平承载力和耗能能力较现浇混凝土剪力墙有所提高;其承载力随着轴压比的增大而增大;实验范围内的轴压比对其耗能能力的影响较小。

关 键 词:钢管混凝土  叠合剪力墙  轴压比  承载力  抗震性能

Abstract:Cyclic tests were carried out on a conventionally reinforced concrete shear wall and three sandwich shear walls with concrete filled steel tubes (SW-CFT). The vertical compression forces on the experimental specimens were varied. The failure mode and hysteretic behavior of each experimental specimen under the combined vertical compression and lateral cyclic loading were evaluated. The equations to calculate the wall lateral resistances associated with the yielding states were derived. The experimental specimens were also simulated by the computer program-XTRACT. Comparisons revealed that the derived equations and the computer model both provide reasonable predictions for the wall resistances. The result show that the SW-CFTs exhibited high horizontal bearing capacity and energy consumption. In addition, the axial compression ratio is proportional to the strength exaltation and has only marginal effects on the seismic behavior of the SW-CFTs within the test range in this study.
Keywords:concrete filled steel tube  sandwich shear wall  axial compression ratio  bearing capacity  seismic behavior
