In order to study the fatigue properties of RC beams reinforced with TRC,ten RC beams were made at first.And nine beams among them were strengthened with TRC; one beam wasn't strengthened as comparison. Then,threepoint bending loading of fatigue test was utilized to study the influence of reinforcement form,percentage of textile reinforcement,reinforcement ratio and damage degree of beams on cracks and deformation development. The results show that the fatigue life of RC beams can be significantly improved ...
