摘要
在已有试验数据的基础上，分析了轴心受压下复合方箍约束砼抗压强度随含箍特征值λｖ和箍筋间距Ｓ的变化规律，提出了方箍约束砼轴心受压短柱承载力的计算公式，该公式适用于普通强度砼和高强度砼（Ｃ２０～Ｃ８０）
Based on the experimental datas,the author analyses how the strength of the conctrete confined by overlapping hoops under uniaxial compression varies with the characteristic value and spacing of hoop.The formula to calculate the load-bearing capacity of the concrete short column are confined by overlapping hoops under uniaxial compression.The formula is suitable for the general strength concrete and the high strength concrete.
