摘　　要：针对《混凝土结构加固设计规范》(GB 50367—2013)和《公路桥梁加固设计规范》(JTG/T J22—2008)在纤维复合材加固钢筋混凝土偏心受压构件中计算方法的差异,在比较两种规范方法内容的基础上,通过算例采用纤维模型法对两种规范方法的结果偏差进行了分析对比,并提出了相应的修正方法。The calculation methods for reinforced concrete(RC)eccentric compression members strengthening with FRP vary in Code for design of strengthening concrete structure and specifications for strengthening design of highway bridges.This paper compared the method content in these two codes.Based on that,calculations by fiber model approach and the code methods were conducted through a case study.This research analyzed and drew the result differences betweem them,proposed a corresponding modified method.
