摘　　要：碳纤维布与钢板复合加固钢筋混凝土梁是一种新型加固方法,通过12根试件的试验,对复合加固梁的截面延性进行计算分析.在普通钢筋混凝土梁截面延性理论计算基础上,根据复合加固特点,考虑到钢筋及钢板的屈服先后次序及混凝土应力状态的不同,对不同状态下的延性进行计算分析.Strengthened RC beams with carbon fiber reinforced polymer and steel plate is a new strengthening method. Based on experiments of the 12 combination strengthened members, the ductility calculation analysis of combination strengthened RC beams has been conducted. On the foundation of ductility theory of RC beams, according to the characteristic of combination strengthening method, the different status＇ ductility calculation have been presented with consideration of the two aspects： the turn of reinforcement bar＇ s bending and steel plate＇ s bending, and the different strain state of concrete.
