【摘要】：对FRP板加固钢梁抗弯承载力的受力性能进行试验研究,研究结果表明钢梁底部粘贴FRP板对提高钢梁抗弯承载力有较大作用,但FRP板最大拉应变远低于其极限拉应变;粘贴FRP板对提高钢梁刚度有限,且破坏时FRP为滑脱破坏,易导致加固突然失效,挠度迅速增加。最后指出FRP板加固钢梁的重点发展方向。
[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.
