根据 12根配有中间筋的钢筋混凝土约束短柱试验与分析 ,建立了弯、剪、压复合应力状态下构件受力分析的力学模型 ,由此导出了考虑中间筋作用的构件抗剪承载力计算公式。通过对比表明 ,公式计算值与试验值吻合较好 ,对于钢筋混凝土约束短柱的抗剪设计与计算具有实用的参考价值。 According to the experiment and analysis of 12 reinforced concrete confined short columns with middle reinforcement, the mechanical model of the component analysis under the composite stress conditions of bending, shearing and compression was established, and the shear capacity of the member considering middle reinforcement was deduced Calculation formula. The comparison shows that the calculated values ​​are in good agreement with the experimental values, which is of practical value for the shear design and calculation of RC confined stub columns.
