摘　　要：为了进一步研究碳纤维(Carbon Fiber Reinforced Polymer,CFRP)加固混凝土短柱轴心受压力学性能,根据合理拱轴线、应力公式及混凝土强度模型,推导出CFRP布加固柱修正后的抗压承载力公式,并通过理论计算和ABAQUS有限元分析验证公式的正确性。In order to further understand the mechanical properties of carbon fiber reinforced polymer（CFRP） reinforced con-crete short columns under axial compression ,the study on the bearing capacity formula of the columns was carried out .Accord-ing to the reasonable arch axis ,stress formula and the concrete strength ,the revised bearing capacity formula of the CFRP sheet reinforced column was deduced and then verified with theoretical calculation and ABAQUS finite element analysis .

关 键 词：CFRP布 有效约束系数 承载力公式 ABAQUS
