摘　　要：利用极限平衡法,通过分析加固率对约束混凝土性能的影响,对文献中的实验数据进行拟合,导出了碳纤维约束混凝土短柱在轴心受压状态下的抗压强度计算公式,并引用文献中的实验数据与该公式计算结果进行对比,两者吻合较好。By means of limit equilibrium method, based on the analysis about the influence of reinforcement degree on the behavior of confined concrete, the formula for strength of short concrete columns confined with CFRP under axial compression is derived by imitating the experimental data in reference. The proposed formula has been verified by the tests available in literature.
