| 摘 要： | GFRP变形筋的外形是影响GFRP筋与混凝土粘结性能的重要因素。本文利用拔出试验研究8种不同外形的GFRP变形筋与混凝土之间的粘结性能,比较了不同外形的GFRP变形筋的粘结强度。试验结果表明,GFRP变形筋的粘结强度较高,最佳肋间距不应超过直径的2.5倍,肋高度应不小于直径的3%。

| Abstract: | The surface form of deformed GFRP rebars is the main factor affecting the bond behavior between GFRP rebars and concrete.This paper uses the pull-out test to study the bond behavior of deformed GFRP rebars with 8 different surfaces to concrete and compares the bond strength.This study shows that the bond strength of deformed GFRP rebars improves obviously,the optimal spacing of ribs should be less than 2.5 times of the rebar dia-meter and height of ribs should be more than 3% of the diameter. |

| Keywords: | deformed GFRP rebars integral rib bond behavior pull-out test |
