【摘要】：對(duì)FRP板加固鋼梁抗彎承載力的受力性能進(jìn)行試驗(yàn)研究,研究結(jié)果表明鋼梁底部粘貼FRP板對(duì)提高鋼梁抗彎承載力有較大作用,但FRP板最大拉應(yīng)變遠(yuǎn)低于其極限拉應(yīng)變;粘貼FRP板對(duì)提高鋼梁剛度有限,且破壞時(shí)FRP為滑脫破壞,易導(dǎo)致加固突然失效,撓度迅速增加。最后指出FRP板加固鋼梁的重點(diǎn)發(fā)展方向。
[Abstract]:The experimental study on the flexural bearing capacity of steel beams strengthened with FRP plates shows that the bonding of FRP plates at the bottom of the steel beams plays an important role in improving the flexural capacity of steel beams. However, the maximum tensile strain of FRP plate is much lower than its ultimate tensile strain. The adhesion of FRP plate to improve the stiffness of steel beam is limited, and the FRP is slippage when the steel beam is destroyed, which easily leads to the sudden failure of reinforcement and the rapid increase of deflection. Finally, the key development direction of strengthening steel beam with FRP plate is pointed out.
