摘　　要：通过结构测试,获得了1根未加固预应力砼梁以及3根粘贴不同层数CFRP加固预应力砼梁在低周反复载荷作用下的受力和破坏情况。试验结果表明,CFRP加固预应力砼梁的效果是明显的,同时对已经开裂的预应力砼梁也具有一定的加固效果;但加固效果与CFRP层数并非成正比。Through testing,the force and the damage that 1 root structure of prestressed concrete beams strengthened and 3 different layers CFRP reinforced stickup prestressed concrete beams under cyclic loading are obtained.The test results show that CFRP reinforcement effect of prestressed concrete beams is obvious,at the same time the cracking of prestressed concrete beam also has certain reinforcement effect,but with CFRP reinforcement effect is proportional to the number of layers.
