摘　　要：为研究T形双波纹钢板混凝土组合剪力墙的抗震性能,以轴压比、波纹钢板形式、翼缘宽度和剪跨比为变化参数,完成了5个试件的拟静力加载试验。基于试验中观测的破坏形态和滞回曲线,对T形双波纹钢板混凝土组合剪力墙的破坏规律和抗震性能进行了分析。试验结果表明:在低周反复荷载作用下试件破坏形态表现为压屈和受拉破坏,破坏发生在腹板端柱底部,滞回曲线呈捏拢的S形,具有非对称性;波纹形状对试件整体抗震性能影响不大;随着轴压比的提高,核心混凝土的约束作用得到加强,水平承载力提升较大,破坏时位移减小,延性变差;增大翼缘宽度可以减小强度退化程度;减小剪跨比可以显著提高试件的初始刚度和水平承载力,但耗能能力变差。To study the seismic behavior of T-shaped double skin profiled composite(DSPC)shear wall,a quasi-static experiment for five specimens was carried out.The parameters included the axial load level,corrugated shape,flange width and shear span ratio.Based on observing failure phenomena and lateral load-displacement hysteretic curves,the failure law and seismic behavior of DSPC shear wall were analyzed.Experimental results indicated that the failure patten of specimens present as tensile failure and buckling failure,the failure occurred at the bottom of the column at the edge of the wed;the hysteretic curves are unsymmerical and show a pinched“S”.corrugated shape has no obvious influence on the seismic behavior of the specimens;with the increase of axial load level,the restrainting effect of core concrete is strengthened,the lateral bearing capacity increases greatly,the displacement at failure and the ductility coefficient decrease significantly;increasing the flange width can inhibit the strength degradation;reducing the shear span ratio can significantly improve the initial stiffness and lateral bearing capacity of the specimens,but the energy consumption capacity becomes worse.
