摘　　要：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。Based on the tests of 12 short restrained reinforced concrete columns bending in two directions with intermediate longitudinal bars,the deformation capacity and failure characteristic of short columns in different shear span ratio are analyzed.The effects of intermediate longitudinal bars on such shear mechanisms as the shear bearing capacity and longitudinal bars′ strains of short columns are studied.The essential theoretical and experimental basis has been provided for establishing the analysis model,by which the shear bearing capacity of short restrained reinforced concrete columns under complex stresses can be calculated.
