摘　　要：对玻璃钢板加固混凝土的挠度进行了试验研究和有限元分析,研究了不同玻璃钢板长度、厚度对挠度的影响,得到了挠度随玻璃钢板长度、厚度变化的规律,为加固梁的变形计算提供依据,有限元计算结果与试验结果吻合较好.The paper focuses on experimental study and finite element analysis of the deflection in concrete beams strengthened with Glass Fiber Reinforced Polymer （GFRP） plates. The deflection influenced by different length and thickness of GFRP plates is investigated, and the regularity of deflection with different length and thickness of GFRP plates is obtained, which provides basis for displacement calculation of reinforced concrete beams. Comparison between FEA results and experimental data show that FEA method is satisfactory.
