中文摘要：

基于3榀缩尺比为1：2.5的单层单跨型钢再生混凝土框架-再生混凝土空心砌块填充墙结构在低周反复荷载作用下的试验研究,采用有限元分析程序Perform-3D对该结构进行非线性分析,研究水平荷载作用下结构的出铰机制,轴压比、宽高比对其承载力、刚度及延性的影响,并将计算结果与试验结果进行对比,两者较为符合.同时对试件承载力与顶点位移关系F-D曲线的影响因素进行分析,结果表明：随着轴压比的增大,框架的水平承载力及初始刚度有所提高,延性降低;随着宽高比的增大,框架的水平承载力及初始刚度提高,但后期刚度退化加快,延性降低.

英文摘要：

Basedonthe experimental study ofthree 1/2.5-scaledmodel ofone-bay and one-story steel reinforced recycled concrete frame-infilled wall with recycled concrete hollow block under low cyclic reversed loading, the software Perform-3D was used for nonlinear finite element analysis on the frame to find out the subsequence of plastic hinges, the load-bearing capacity, the stiffness and the ductility was investigated under the horizontal loading considering the parameters such as the axial compression ratio, and the width-height ratio. The calculating results agreed well with the test results. The factors affecting the F-D curve were analyzed. The results show that with the increase of the axial compression ratio, the horizontal load-bearing and the initial stiffness of the frame increased, but the ductility of the frame decreased. With the increase of the width-height ratio, the horizontal load-bearing and the initial stiffness of the frame increased, but the stiffness of the frame degradated rapidly at the later loading stage and the ductility of the frame decreased.
