摘　　要：将钢板带设置于高强混凝土剪力墙中替代钢筋形成内置钢板带高强混凝土组合剪力墙。为研究该类组合中高剪力墙的抗震性能,对4片内置钢板带高强混凝土组合剪力墙进行拟静力低周反复试验,在轴压比恒定的情况下研究设置钢板带的配钢率及钢板带的位置对其滞回性能、耗能性能,变形能力、强度衰减的影响。结果表明:内置钢板带高强混凝土组合剪力墙在保证钢板具有有效的侧向约束防止发生面外屈曲的同时,提高了钢板带组合墙体的抗裂能力、承载力及耗能能力。在配钢率一定的情况下,钢板位置位于墙身两侧的钢板剪力墙具有更好的延性及耗能能力。The steel plate is set in the high-strength concrete shear wall to replace the steel bar to form the composite shear wall with steel plate and high-strength concrete.To study on the seismic performance of the composite shear wall,4 composite shear walls are carried out by low cycle test.The influence with the ratio of and the position of the steel plate on the hysteretic behavior,energy dissipation capacity,deformation capacity and strength attenuation are studied under the condition of constant axial compression ratio.Test results indicate that the steel plate with high-strength concrete and composite shear walls will ensure concrete lateral restraints and prevent the steel plate of out-plane buckling which also improve the wall crack resistance,bearing capacity and energy dissipation capacity.The steel plate shear wall with a certain percentage of steel and proper location will take on better ductility and energy dissipation capacity.
