| 摘 要： | 研究了PVA纤维混凝土改性梁的抗弯性能,通过对不同配筋率和不同PVA纤维体积掺量的混凝土受弯梁的试验测试,研究混凝土中加入PVA纤维后的增强与增韧作用效果.结果表明:PVA纤维能有效提高混凝土梁的初裂荷载和极限承载力,PVA纤维的掺入使混凝土由脆性破坏变为延性破坏,明显改善了混凝土变形能力.

| Abstract: | Bending performance of PVA fiber-reinforced concrete beam was studied.The experiment of PVA fiber-reinforced concrete beams with different steel ratio and PVA ratio was done to test whether the load-bearing and toughness of the PVA fiber-reinforced concrete was increased.The results indicate that the PVA fiber can improve the initial cracking load and the ultimate bearing capacity.The deformation ability of concrete was obviously changed after PVA fiber was added,and the failure mode was changed from brittle failure to ductile failure. |

| Keywords: | PVA fiber concrete beam ultimate bearing capacity deformation |
