摘　　要：该文运用ANSYS有限元软件,建立三种结构模型,将I型GFRP加固梁和U型GFRP加固梁与同等配筋的普通混凝土梁进行非线性有限元对比分析,从整理的有限元计算结果中讨论了玻璃纤维布对钢筋混凝土梁受力状态的贡献。The article uses ANSYS finite element software to set up three structural models for carrying out the nonlinear finite element contrast and analysis of I-type GFRP reinforced beam and U-type GFRP reinforced beam with the equivalently reinforced normal concrete beam,and discusses the contribution of fiberglass cloth to the bearing status of steel reinforced concrete beam according to the sorted-out finite element calculation result.
