摘　　要：为研究低周反复荷载下T型双波纹钢板混凝土组合剪力墙的受力性能,对5个T型双波纹钢板混凝土组合剪力墙进行了低周反复加载试验。基于试验数据,分析了T型组合剪力墙的破坏模式、滞回曲线、变形能力及耗能能力,重点研究了边缘约束条件、波纹类型以及轴压比不同变化参数对T型组合剪力墙抗震性能指标的影响规律。研究结果表明:T型双波纹钢板混凝土组合剪力墙破坏模式主要有压屈破坏和压弯破坏两种;设置边缘约束构件是提高T型双波纹钢板混凝土组合剪力墙承载能力和变形能力的关键因素;纵向窄波纹钢板对内部混凝土的约束能力更强,在低周反复荷载下两者协同工作性更优,而横向窄波纹钢板试件强度退化最严重;采用全截面塑性设计方法进行T型双波纹钢板混凝土组合剪力墙正截面承载力计算,试验值与计算值吻合良好;T型双波纹钢板混凝土组合剪力墙具有较好的承载能力和变形能力,可适用于高层及超高层建筑结构中。To investigate the mechanical behavior of T-shaped double corrugated steel plate concrete composite shear wall under low cyclic loading,five specimens were tested.The failure mode,hysteretic curves,deformation capacity and energy dissipation capacity of the T-shaped composite shear walls were analyzed.The influence of the edge constraint conditions,corrugation types and axial compression ratio on the seismic performance indicators of T-shaped composite shear walls were studied.The results show that the failure modes of T-shaped double corrugated steel plate concrete composite shear wall can be divided into compression yield failure and compression bending failure.Setting edge restraint members is the key factor to improve the bearing capacity and deformation capacity of T-shaped double corrugated steel plate concrete composite shear wall.The longitudinal-narrowly corrugated steel plate can better constrain the inner concrete,and the they work better under low cyclic loading,while the transverse-narrowly corrugated steel plate shows the most severe degradation in strength.The full-section plastic design method was employed to calculate the bearing capacity of the normal section of the T-shaped double corrugated steel plate concrete composite shear wall,the experimental values are consistent with the calculated values.T-shaped double corrugated steel plate concrete composite shear walls have good bearing capacity and deformation capacity,which can be applied to high-rise buildings and super-high-rise buildings.
