| 摘 要： | 通过19根CFRP布包裹高强混凝土短柱轴心受压试验,研究截面形状和不同包裹量对包裹后高强混凝土短柱强度和变形的影响。试验结果表明:采用CFRP布包裹高强混凝土柱在提高承载力和变形方面仍然有效,但其对变形的改善作用远大于其对承载力的提高;依据试验结果确定了CFRP布约束高强混凝土强度和应变的计算模型。

| Abstract: | By the axial compression tests on a total of 19 high-strength concrete columns wrapped with CFRP cloth,the influence of shape section and different confinement ratio on the axial compressive strength and ductility is studied.The experimental results indicate：high-strength concrete columns wrapped with CFRP in increasing the bearing capacity and ductility of concrete columns is still valid,its effect on the improvement of ductility is much greater than its capacity,based on experimental data,the calculation model of strength and strain are obtained by the regressive analysis of results. |
