摘    要:为研究轴压比对波形钢板混凝土组合剪力墙的影响。利用ABAQUS有限元软件对不同轴压比的竖向、水平钢板混凝土组合剪力墙进行非线性分析,以考察轴压比对波形钢板混凝土组合剪力墙的滞回性能、变形能力、抗侧承载力、抗侧刚度以及耗能能力的影响,并对其分析结果进行了试验验证。有限元分析结果表明:当轴压比在0.15~0.45范围内且逐步增大时,竖向波形钢板混凝土组合剪力墙的承载能力和耗能能力随之增强,其延性和变形能力反之减弱,当轴压比超过0.6时,剪力墙的抗震性能表现较差;当轴压比在0.15~0.3范围内且逐步增大时,水平波形钢板混凝土组合剪力墙的承载能力随之增强,其延性和变形能力反之减弱,但对耗能能力影响不显著,当轴压比超过0.45时,剪力墙的抗震性能表现较差,当轴压比超过0.6时,其极限状态下的位移角低于位移角限值要求;轴压比在0.15~0.3范围内,且竖向、水平波形钢板混凝土组合剪力墙的轴压比相同时,前者表现出更好的抗震性能。为了确保有限元分析结果的可靠性,后续对两个剪力墙试件进行了拟静力试验,试验结果表明:有限元分析结果与试验结果吻合度较高,因此有限元分析所得结果,可为后续实际工程提供参考。

关 键 词:波形钢板混凝土组合剪力墙  轴压比  有限元分析  拟静力试验  抗震性能

Abstract:In order to study the influence of axial compression ratio on corrugated steel plate-concrete composite shear walls(SPCSW).Nonlinear analysis of vertical corrugated steel plate-concrete composite shear wall(SPCSW-2) and horizontal corrugated steel plate-concrete composite shear wall(SPCSW-3) based on ABAQUS finite element software with different axial compression ratio, in order to investigate the effects of axial compression ratio on hysteretic performance, deformation capacity, lateral bearing capacity, lateral stiffness and energy dissipation capacity of SPCSW, and the analysis results are verified by experiments. The results of finite element analysis show that when the axial compression ratio is in the range of 0.15 to 0.45 and increases gradually, the bearing capacity and energy dissipation capacity of SPCSW-2 are increased, and its ductility and deformation capacity are weakened. When the axial compression ratio exceeds 0.6, The seismic performance of shear wall is poor. When the axial compression ratio is in the range of 0.15 to 0.3 and increases gradually, the bearing capacity of SPCSW-3 increases, and its ductile and deformation capacity weakens, but it has no significant effect on the energy dissipation capacity. When the axial compression ratio exceeds 0.45, the seismic performance of shear wall is poor. When the axial compression ratio is more than 0.6, the displacement angle in the limit state is lower than the limit requirement of displacement angle. When the axial compression ratio is in the range of 0.15 to 0.3 and the axial compression ratio of SPCSW-2 and SPCSW-3 is the same, the former shows better seismic performance. In order to ensure the reliability of the finite element analysis, a quasi-static test is carried out on the two shear walls. The experimental results show that the finite element analysis results are in good agreement with the experimental results, so the results of finite element analysis can provide a reference for the follow-up practical engineering.
Keywords:corrugated steel plate-concrete composite shear wall  axial compression ratio  finite element analysis  Seismic performance
