摘　　要：采用GFRP筋增强混凝土梁的方法,提高了混凝土梁的刚度和挠度,有限元软件建模和对比分析表明,GFRP加固的钢筋混凝土梁挠度降低了很多,在一定程度上可以减轻钢筋混凝土构件的自重;所采取的玻璃纤维布加固混凝土技术比传统的加固技术效果要好,GFRP-混凝土复合材料结构可以有效提高结构的强度和刚度。该研究对混凝土梁的改进具有一定的理论和实践指导意义。The stiffness and deflection of concrete beams were improved by using glass and steel reinforced concrete beam method, a detailed finite element software modeling and comparative analysis showed that GFRP reinforced concrete beam deflection was reduced a lot, in a certain extent, it can reduce weight of reinforced concrete structures, GFRP concrete composite structure can effectively improve the structural strength and stiffness, which indicates that the effects of taking GFRP reinforced concrete technology is better than that of the traditional technique. The research for the improvement of concrete beams has some theoretical and practical significance.
