摘要(Abstract):

通过 9根碳纤维布加固补强钢筋混凝土梁的试验 ,主要研究碳纤维布用量对钢筋混凝土梁受弯性能的影响和作用。试验研究表明 ,使用碳纤维布来提高钢筋混凝土受弯构件正截面承载力的方法是有效的 ,粘贴碳纤维布后 ,试验梁的受弯承载力明显提高。此外 ,还编制了计算机分析程序进行理论分析 ,并提出了一种简化的受弯承载力计算方法 ,该方法与试验数据和理论分析可较好地吻合 ,可以满足实际工程设计的要求。
Nine simply supported beams strengthened with carbon fiber sheet (CFS) are tested.Experimental results indicate that CFS can evidently increase the yield load when the longitudinal reinforcement reaches its yield point and the ultimate load of the reinforced concrete beams subjected to bending.The hypothesis of plane sections is also verified by the experiment.Based on the experiment,a computer analysis program is developed and a simplified design formula is proposed.The design method can meet the engineering requirements.
