摘要

近表面贴装CFRP条加固RC结构技术的关键在于不同界面(包括CFRP-环氧界面和环氧-混凝土界面)的粘结性能,其粘结性能受多种因素的影响。本文采用简易剪切试验装置对CFRP条与混凝土界面的粘结性能进行了试验研究。考察了混凝土强度、沟槽宽度、沟槽与试件边缘的距离、粘结长度等因素的影响。对试验中获得的数据和观察到的现象进行了分析。

Experimental Study on Bond Performance of Near-Surface-Mounted CFRP Strips-Concrete Interface
The key of the technique to strengthen RC structures with near-surface-mounted CFRP strips lies in the bond performance of different interfaces (including CFRP-epoxy interface and epoxy-concrete interface), which may subject to the effect of many factors. It is presented here an experimental study on the bond performance of CFRP strips-concrete interface using a simple shear test set-up. The effect of different factors, including concrete strength, groove width, distance between the groove and edge of the specimen and bond length etc., are examined. Data obtained and phenomena observed during the test are all analyzed.
