摘要
在低周往复荷载试验的基础上,对带端柱的钢筋混凝土剪力墙的承载力、耗能能力及刚度退化进行有限元分析,采用控制变量法,改变单一元素,利用ABAQUS软件模拟分析端柱内箍筋强度等级和轴压比对带端柱剪力墙体抗震性能的影响.分析结果表明:有限元分析结果与试验结果吻合较好,有限元分析可以作为试验的有效补充;提高箍筋强度等级使剪力墙结构的承载能力得到提高,对结构的耗能能力及刚度退化影响较小;随着一定范围内结构的轴压比的提高,结构的承载力有所增强,初始刚度增加,耗能能力降低.
On the basis of low cycle loading test, bearing capacity, energy dissipation capacity and the stiffness degrada-tion of the reinforced concrete shear wall with end colunm are conducted a finite element analysis on. With the control variable method and ABAQUS software, changing a single element, this paper analyze the influence of factors such as the stilTup strength grade and axial compression ratio on seisnfic performance of shear walls. The results of analysis indi-cate that the result of finite dement analysis has good agreement with the experimental result and the finite element anal-ysis can be used as an effective supplement to the experiment, hnproving the stirrup strength grade can improve the bear- ing capacity of the shear wall and make little influence on the energy dissipation capacity and the stiffness degradation. Within limits, improving the axial compression ratio can improve the bearing capacity and initial stiflhess of the shear wall. The energy dissipation capacity will reduce at the same time.
