摘　　要：为了研究CFRP约束混凝土棱柱体的受力性能,通过8组CFRP布约束混凝土棱柱体试件的轴心抗压试验,得出应力-应变关系曲线;分析碳纤维布在构件中分布、加固方式等试验参数对构件约束效果的影响。试验结果表明:混凝土棱柱体构件受碳纤维约束后承载力、延性提高的渐线形变化。In order to study the properties of CFRP confined concrete column,the test on eight groups of columns subjected to axial loading were conducted in this study.The stress-strain curves were obtained.In the component analysis of CFRP reinforced mode of distribution,test parameters of component constraint effect.Test results show that the concrete prism body component by carbon fiber constraint bearing capacity,ductility improve gradually linear change.
