| 摘 要： | 为了对钢筋混凝土梁进行抗剪加固试验研究，采用碳纤维和玻璃纤维两种材料分别对钢筋混凝土梁剪压区进行加固，并进行了对比试验，试验梁两端简支，在梁跨方向三分点处进行两点加载试验，量测试验梁的应变和变形，观测了裂缝形态和发展趋势。结果表明，采用纤维对钢筋混凝土梁进行剪切加固后，其抗剪强度明显提高，但对梁的刚度和变形影响较小。

| Abstract: | Carbon fiber reinforced plastic (CFRP) and glass fiber reinforced plastic (GFRP) were used for the strengthening. Both strain and deformation were measured. Concrete crack development, crack distance and crack width were observed as well. The results show that RC beams strengthened by CFRP or GFRP can increase the shear bearing capacity of the beams, but has little effect on the beam stiffness. |
