摘　　要：通过对钢筋混凝土梁用 GFRP片材进行抗弯加固试验 ,研究其受弯破坏特征、对梁的极限承载力、刚度等的影响 .得出平截面假定适用、加固梁初期效果不明显 ,片材厚度、片材端部到支座的距离为主要影响因素 ,而对锚固端 U形加强条进行加强处理的效果明显等结论 .A test of bending resistance and reinforcement is carried out on RC beam by applying sheet of fibre glass reinforced plastics(FRP). A study and analysis is given to the traits of bending and rupture of RC beam reinforced by applying FRP and to the effect of FRP on ultimate bearing capacity and stiffness of the beam. As it is concluded by the above mentioned studies, the horizontal section assumption is suitable for use; the initial effect of reinforced beam is indistinct,the thickness of sheet and the distance from the end of sheet to the pedestal are the main influencing factors, and the strengthening effectof U shaped reinforcing stripe at the anchorage end is distinct. These conclusions provide a basis for further theoretical study.
