通过１２根配有中间筋的双曲率钢筋混凝土约束短柱试验，分析了剪跨比不同时构件的破坏特征和变形能力，研究了中间筋对约束短柱抗剪承载力、纵向钢筋应变等抗剪机理的影响，为建立复合应力状态下钢筋混凝土约束短柱抗剪承载力计算的力学模型提供了必要的理论和试验依据。
By using 12 double-curvature reinforced concrete confined short column tests with intermediate ribs, the failure characteristics and deformation capacity of the components with different shear-span ratios were analyzed. The resistance of the middle ribs to the shear capacity and longitudinal steel strain of the short columns was studied. The influence of the shear mechanism provides the necessary theoretical and experimental basis for establishing the mechanical model for the calculation of shear capacity of reinforced concrete restrained short columns under compound stress.
