[提要]  在20根梁的試驗(yàn)基礎(chǔ)上，對(duì)用碳纖維布加固鋼筋混凝土梁后的抗剪破壞特征、受剪承載力及影響因素進(jìn)行了研究與分析，并提出了受剪承載力計(jì)算公式，可供工程應(yīng)用參考。
[關(guān)鍵詞]  抗剪 混凝土梁 加固  碳纖維布 破壞特征  受剪承載力

Based on the tests of twenty beams, the failure type, the ultimate strength and the influence factors of
reinforced concrete beams strengthened with externally bonded carbon fiber reinforced sheet are researched and analysed. The formula for estimating the shear capacity is put forward, which can give reference to application.
Keywords: shear; beam; strengthening; carbon  fiber reinforced sheet; failure type; shear strength
