摘　　要：对底层框架-配筋暖砖墙体的抗震性能进行有限元分析,构建了5片不同配筋方式、混凝土强度等级、洞口以及高宽比的墙体有限元模型,对底层框架-配筋暖砖墙体进行了低周反复荷载试验模拟,详细分析了各个参数对墙体抗震性能的影响.研究结果表明:混凝土强度等级的提高和配筋率的增加会改善墙体的抗震性能,洞口的存在降低了墙体的极限承载力和变形能力,底层框架尺寸的改变对墙体的抗震性能有很大的影响.This paper makes a finite element analysis of the seismic behavior of the underlying framework-reinforced insulation brick wall.The finite element model of 5 walls with different reinforcement form,concrete strength grade,opening and aspect ratio is established.Through carrying out the low-cycle repeated load test simulation of the wall,the effects of various parameters on the seismic behavior of the wall are analyzed in detail.The result of research shows that:The increase of concrete strength grade and reinforcement rate can improve the seismic behavior of the wall,while the existence of opening can reduce the ultimate bearing capacity and deformability of the wall,and the change of the size of underlying framework has a great influence on the seismic behavior of the wall.
