碳纤维加固混凝土柱粘贴方法的试验研究

Trial research on the pillar reinforced method of the carbon fiber glues to stick to concrete

对12根混凝土短柱采用不同粘贴方法和搭接长度进行试验研究.结果表明粘贴方法不同对加固效果有影响,用碳纤维布加固混凝土柱可以提高构件的承载能力、增加柱的抗变形性能和改善延性.证明了搭接长度的安全值,并提出了其建议值,为碳纤维材料在加固技术中的应用提供了经验积累.

Trial research has been made for 12 concrete short pillar through taking different sticking methods and connecting length in this paper. The results show that the different sticking methods have dissimilarity to the reinforcing effect. The reinforcing the concrete pillar with the carbon fiber cloth can improve the loading ability of comporents, anti-deformation and ductility. A safe value of the connecting length is proved and the suggestion value is given. It will provide the experience for the application of the reinforcing technique for the carbon fiber material.
