摘　　要：采用分段封闭约束高强箍筋构造方式,按性能设计理论分别设计了6个带端柱高性能混凝土剪力墙,进行拟静力试验;根据试验研究结果,以开裂点、屈服点、峰值点和极限点为特征点,将剪力墙截面的弯矩-曲率骨架曲线简化为4折线型;基于应变平截面假定,考虑边缘约束构件的约束效应,分别推导了带端柱高性能混凝土剪力墙的开裂、屈服、峰值和极限点的弯矩和曲率表达式,表达式的计算值与试验值符合良好.To improve the deformability of high performance concrete shear wall（HPCW）,a partial confining stirrup in six HPCWs with edge columns was developed and verified by the pseudo-static test.According to the experimental result,the moment-curvature skeleton curve of the shear wall cross-section is simplified as four linear through cracking point,yield point,peak point and the ultimate point.Based on the strain plane-section assumption,the cracking,yielding,the peak and the ultimate bending moment as well as the curvature expressions are derived.The effects of confined end-zones are taken into account.Results show that the calculated values are in good consistency with the experimental data.
