以型钢高性能混凝土剪力墙试验研究为基础,采用有限元软件ABAQUS建立了型钢高性能混凝土剪力墙的非线性有限元模型,考虑材料非线性,模拟了加载全过程和混凝土开裂等受力性能,数值计算结果与试验结果吻合较好。在此基础上,分析了影响型钢高性能混凝土剪力墙变形能力的主要因素,包括轴压比、配钢率、高宽比和配箍特征值。通过建立的有限元模型,分析了不同轴压比条件下约束边缘构件长度与配箍特征值的设置要求。
Based on the experimental study of steel high performance concrete shear wall, the nonlinear finite element model of the high performance concrete shear wall of the section steel was established by the finite element software ABAQUS. The material nonlinearity was considered to simulate the whole process of loading and cracking of concrete The performance and numerical calculation agree well with the experimental results. On this basis, the main factors affecting the deformation capacity of high performance concrete shear walls of steel mills are analyzed, including axial compression ratio, steel ratio, aspect ratio and the characteristic values of the bail. Through the established finite element model, the requirements for setting the length of restraining edge component and the characteristic value of ferrule under different axial compression ratio are analyzed.
