摘　　要：进行了9个高宽比不大于1的钢管高强混凝土剪力墙试件的拉剪性能试验,研究了剪力墙中钢管高强混凝土含量、高宽比(剪跨比)、竖向分布筋配筋率、管外混凝土强度、初始拉力水平等因素对其在拉力和剪力共同作用下受力性能的影响。试验结果表明,钢管高强混凝土剪力墙在高轴拉力作用下仍具有很高的受剪承载力和良好的延性。在统计分析的基础上,提出了钢管高强混凝土剪力墙拉剪承载力计算式,计算结果与试验结果吻合良好。Nine specimens of shear wall with steel tube-confined high-strength concrete which aspect ratios are not larger than one were tested under axial tensile force and horizontal shearing force in order to study its tensile-shear performance. The influences of the amount of steel tube-confined high-strength concrete, vertical reinforcement ratio, strength of concrete outside the tube, axial tensile force as well as aspect ratio were studied during the tests. Results show that even under high level of tensile force, the shear wails with steel tube-confined high-strength concrete could still develop high shear capacity and good ductility. Calculation formula for the tensile-shear bearing capacity of shear wall with steel tube-confined high-strength concrete was proposed. The calculate results of the formula are in good agreement with experimental results.
