摘要:
为了研究工字形截面RC剪力墙在地震作用下的变形能力,采用ABAQUS分析了324个工字形RC剪力墙有限元模型,以剪跨比和弯剪比为参数确定了构件破坏形态的判断标准。结合我国规范提出了7个性能水准和6个性能水准限值,根据材料应变和荷载-位移曲线定义了6个性能水准限值的判断准则,并可得到所有模型的位移角。根据破坏形态、轴压比和弯剪比进行统计,得到工字形RC剪力墙的变形指标限值并与构件试验及ASCE41指标进行对比,分析结果表明:提出的破坏形态划分方法预测正确率达85%,能够满足工程需求;利用本文变形限值对试验构件破坏形态的判断结果与ASCE 41基本一致;试验得到的“比较严重破坏”位移角约为本文变形限值的3倍,指标限值具有足够的安全储备。
