摘要
In order to study the effect mechanism of interaction and non-interaction of the hot-wet environment and fatigue loads on the reinforced concrete (RC) components strengthened with carbon fiber reinforced polymer (CFRP), three-point bending fatigue tests of RC beams strengthened with carbon fiber laminate (CFL) under interaction and non-interaction of fatigue load and hot-wet environment of constant temperature of 50℃ and constant humidity of 95% were carried out in this paper.The results show that the fatigue limit of reinforced beams was lower about 13% under the interaction compared with conventional (non-interaction) environmental fatigue testing method.Therefore, interaction of the hot-wet environment and fatigue loads should be considered in the design of the fatigue resistance and durability for RC components strengthened with CFRP used in bridge.
