［摘要］通過工程實例，對《碳纖維片材加固混凝土結(jié)構(gòu)技術(shù)規(guī)程》(CECS146：2003)和《混凝土結(jié)構(gòu)加固設(shè)計規(guī)范》(GB50367—2006)中受彎構(gòu)件正截面加固公式的適用范圍進行分析，發(fā)現(xiàn)在考慮經(jīng)濟因素和安全因素影響的條件下，加固前構(gòu)件的受拉鋼筋配筋率較低的工程不適宜用碳纖維加固，應(yīng)考慮采用其他方法進行加固。繪出了不同混凝土強度等級、可以用于碳纖維加固的受拉鋼筋配筋率的適用范圍參考圖，供在實際工程中參考。

Abstract:Through an example, the application range of the strengthing formulas of nomal section of flexural member in Technical specification for strengthening concrete structures with carbon fiber reinforced polymer laminate(CECS146：2003) and Design code for strengthening concrete structure (GB50367—2006) were discussed. The results show that the
