[摘要]通過(guò)6根矩形截面鋼筋混凝土梁靜力試驗(yàn)，考察了不同玄武巖纖維布粘貼層數(shù)下，加固梁的承載能力及破壞模式，試驗(yàn)表明在鋼筋混凝土梁受拉區(qū)粘貼玄武巖纖維布可有效提高既有損傷鋼筋混凝土梁的抗彎性能。采用ANSYS軟件對(duì)BFRP 布加固既有損傷鋼筋混凝土梁進(jìn)行數(shù)值模擬，并與試驗(yàn)結(jié)果進(jìn)行對(duì)比，驗(yàn)證了應(yīng)用ANSYS有限元軟件對(duì)BFRP布加固既有損傷鋼筋混凝土梁進(jìn)行數(shù)值模擬的有效性。

Abstract: Experiment of six specimens of beams was conducted to study the effect of amounts of BFRP sheets on the ultimate flexural resistance and failure mode of the damage concrete beams strengthened with BFRP sheets. Results showed that the flexural resistance of damage concrete beams could be improved with the CFRP-sheet gluing the bottom of the reinforced concrete beams. Numerical simulation of the damage concrete beams strengthened with BFRP sheets was conducted by ANSYS, and the results of numerical simulation were compared with those of the test results.

Keywords: BFRP sheets; strengthening; damage; numerical simulation
