摘要
设计了40组试件,分别对20,30,50,60,70℃五种不同养护温度和0.8ΔF、1.0ΔF、1.2ΔF三种不同荷载幅下,两种FRP加固钢结构用黏结剂的疲劳性能进行试验研究,通过对两种不同黏结剂在不同养护温度和不同应力幅下的疲劳性能对比,分析养护温度和荷载幅对黏结剂疲劳循环寿命的影响程度,得到较为适宜的养护温度范围为30~50℃,对工程实践具有实际指导意义。
Fatigue properties of two kinds of adhesive binders for FRP strengthened steel structure cured at different temperature,20,30,50,60,70 ℃ were studied under three load amplitudes; By studying the fatigue properties of the two adhesive bonders under different temperature and load amplitudes,the influences of curing temperature as well as load amplitude on the binder fatigue life were analyzed. As a result,an appropriate range of curing temperature of 30 ~ 50 ℃ was brought out,which provided a guide to engineering practice.
