摘要
根据目前工程结构加固的实际情况,以及碳纤维增强复合材料(CFRP)加固钢筋混凝土梁的理论和实验研究结果,分析了二次受力对加固梁的抗弯承载力影响,提出了二次受力条件下碳纤维布加固梁的抗弯承载力计算方法。给出了界限加固量及最大和最小加固量的计算公式。
In accordance with current practical situation of structure strengthening and experimental study and the theory of concrete beams strengthened in bending with carbon fiber reinforced plastics are introduced, analyses the preloading effect on the bending capacity of the reinforced concrete beams, bring up the method for the bending calculation of RC beam strengthened with carbon fiber reinforced plastics sheets under sustaining load. And give out the design formula of the limit strengthen. quantity, Max. and Min. strengthen quantity.
