摘　　要：利用有限元软件ABAQUS分别建立平钢板混凝土组合剪力墙与双层波纹钢板混凝土组合剪力墙有限元模型,对2种钢板混凝土组合剪力墙在低周往复荷载作用下的受力机制及滞回性能进行对比分析,验证波纹钢板代替平钢板的合理性。通过对4种波纹尺寸不同的钢板混凝土组合剪力墙进行对比分析,研究波纹直径与波幅对组合墙体抗震性能的影响规律。结果表明:将波纹钢板代替平钢板,能显著提升墙体的承载能力、耗能能力与整体刚度。波纹直径较小、钢板波折次数较多的组合剪力墙承载能力更强;波纹直径较大、钢板波折次数较少的组合剪力墙整体刚度较强。波幅等于半径的波纹钢板剪力墙具有更强的承载能力和耗能能力,整体抗震性能较好。ABAQUS finite element software was used to establish the finite element model of concrete combined shear wall with flat steel plate and concrete combined shear wall with double-layer corrugated steel plate,respectively,to compare and analyze the force mechanism and hysteresis performance of two kinds of concrete combined shear wall with steel plate under the action of low circumferential recipro‐cating load,and to verify the reasonableness of the corrugated steel plate instead of flat steel plate.The comparative analysis of four types of steel plate concrete combined shear walls with differ‐ent corrugation sizes was carried out to study the influence law of corrugation diameter and wave am‐plitude on the seismic performance of the combined walls.The results show that replacing flat steel plates with corrugated steel plates significantly improves the load carrying capacity,energy dissipa‐tion capacity and overall stiffness of the wall.Combined shear walls with smaller corrugation diam‐eters and a higher number of steel plate corrugations have a higher load carrying capacity;Combined shear walls with larger corrugation diameters and a lower number of steel plate corrugations have a higher overall stiffness.Corrugated steel plate shear walls with a wave amplitude equal to the radius have a stronger load carrying and energy dissipation capacity and better overall seismic performance.
