［摘要］在设防或罕遇地震情况下，超高层建筑底部的混凝土剪力墙在地震作用下会出现偏心受拉的工况。通过对4片受拉混凝土剪力墙试件和1片配置抗滑移钢筋的受拉混凝土剪力墙试件进行拟静力试验，研究受拉混凝土剪力墙的破坏特征、滞回特性、承载力、刚度和耗能能力。研究表明：轴拉力影响混凝土剪力墙破坏过程的裂缝分布和破坏形态；轴拉力可显著降低混凝土剪力墙的承载力、侧向刚度和耗能能力；配置抗滑移钢筋能提高受拉混凝土剪力墙的承载力和耗能能力；《混凝土结构设计规范》（GB 50010—2010）中受拉剪力墙受剪承载力计算公式满足设计的安全要求。

Abstract:In the case of fortification or rare earthquake, the concrete shear wall at the bottom of the super high-rise building appears eccentric tension working condition. The pseudo static tests were conducted on four pieces of tensile concrete shear wall specimens and one piece of tensile concrete shear wall specimen with slip resistant rebar. The failure mechanism, hysteretic behavior, load-carrying capacity, stiffness and energy dissipation ability of the tensile concrete shear wall were studied. Research results show that: axial tensile force impacts fracture distribution and the failure pattern in the failure process of concrete shear wall; axial tensile force can significantly reduce the bearing capacity, lateral stiffness and energy dissipation of the concrete shear wall; configuration of slip resistant rebar can improve the bearing capacity and energy dissipation ability of the tensile concrete shear wall. In the Code for design of concrete structures (GB 50010—2010), the calculation formula of shear capacity of the tensile shear wall can meet the safety requirements of the design.

Keywords:concrete shear wall; slip resistant rebar; axial tensile force
