摘要
针对氯离子侵蚀环境下碳纤维加固钢筋混凝土结构耐久性的问题进行了实验研究,试验结果和理论分析表明,采用碳纤维加固混凝土短柱是可行的,加固后的混凝土短柱的耐久性指标都得到了不同程度的提高,但是不同的加固防护形式,对混凝土短柱的耐久性指标有较大的影响.与此同时,荷载对混凝土短柱的耐久性性能也有一定影响,这主要是因为荷载的存在加剧了混凝土内部微裂缝的发展,同时对碳纤维加固层有一定的负面影响.
This paper mostly aims at studying the durability of loaded RC column that is reinforced by CFRP, Test results of this experiment also can be offered in durability analysis of concrete column. The method of reinforced RC column with CFRP can enhance the durability of concrete in corrosive marine environment, but there are different result according to different methods of reinforce. It needs choose the method of reinforce reasonably. The results indicate that loading has significant effects on corrosion, the loading can accelerate expand of cracks. 1 lilts., 2tabs., 5refs.
