持载与干湿作用下CFRP－高强混凝土黏结性能研究
The bond behavior between high-strength concrete and CFRP under the sustained load and wet-dry cycles
摘要
Abstract
In order to provide reliable reference for the reinforcement of building structures,the bond behavior of high strength concrete with CFRP was studied,considering the effect of wet-dry cycles and sustained load.The 5% NaCl solution was used to simulate seawater,and the self-designed loading device was adopted to apply sustained load.Based on this,the bond performance of high strength concrete with CFRP was analyzed with the doubled-sided shear test.The results indicate that with the increase of wet-dry cycles,the failure mode of in-terface alters and,the bonding strength,peel load and the terminal slip reduces gradually.Moreover,sustained load will aggravate interface damage and accelerate the transition speed of the failure mode of interface.关键词
