碳纤维布加固钢筋混凝土梁正截面承载力设计方法

摘要

The practical design methods for reinforced concrete members strengthened with fiber reinforced plastics is presented,and detailed calculation process are also showed.The structure initial strain is considered in the practical design method and its calculation formula is simplified.Lastly,the practical design method is proved to be brief and applied by two practical examples given and can be taken as reference for design engineers.%文章探讨了目前碳纤维复合材料加固钢筋混凝土受弯构件正截面承载力的一般设计方法,综合了《公路桥梁加固设计规范》（JTG/T J22—2008）推荐使用的方法和工程用一般实用设计方法的优点,提出了一种简化的正截面承载力设计方法,该方法考虑了结构初始应变的影响;给出了相应的计算简化公式和详细计算过程;算例分析表明,该简化设计方法误差较小,计算简捷合理、实用性强,可供工程设计人员参考。
