| 摘 要： | 分析研究了粘贴高强复合纤维加固受弯构件的受力过程，探讨了加固后钢筋混凝土梁正截面的破坏特征、受力特点以及影响因素，并提出正截面强度计算公式。试验结果表明：钢筋的配筋率与复合纤维的粘贴量对加固效果影响较大；实施桥梁构件加固时，要考虑加固前混凝土和钢筋已存的应力应变；复合玻璃纤维能有效地抑制裂缝的开展与延伸，为今后研究提供了参考。 |
| 关 键 词： | 高强复合纤维 受弯构件 加固 承载能力 |

| Abstract: | The behavior of flexural members strengthened with advanced glass-fibre composites was studied. By discussing the load-deformation process, flexural failure characters and the influencing factors, a method for the determination of the ultimate strength of such members was put forward, The testing results indicated that the reinforcement ratio and the affixing amount of advanced glass-fibre composites had great influence on the strengthening effects, The existing stress-strain should be considered before strengthening the flexural members. The glare-fibre composites could efficiently prohibit the cracks from extension and elongation, which will provide reference for the further research. |
| Keywords: | advanced glass-fibre composites flexural members strengthening load bearing capacity |
