摘要(Abstract):

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 experiment of steel high performance concrete(SHPC) walls,nonlinear finite element analysis was performed to simulate the complete process of the loading and concrete crack of SHPC walls by ABAQUS.The nonlinear characteristic of material was taken into account in the models.The reliability of the finite element model was verified through the comparison of analysis results and experimental results.Based on the proposed model,parametric analysis was carried out to study the effect of axial load ratio,height-width ratio,stirrup characteristic value,and steel ratio on the seismic behavior of SHPC walls.The stirrup characteristic values were proposed to ensure the SHPC walls under different axial load ratios to meet the deformation capacity of drift ratio of 1/120,1/100 and 1/80,respectively.
