| 摘 要： | 为了进一步研究表层嵌贴FRP抗弯加固钢筋混凝土梁的性能,本文结合了已有试验中的14根试件建立了三维非线性有限元模型,主要分析了加固梁的极限承载力、荷载-位移曲线以及破坏模式。计算结果表明:采用本文有限元方案分析的结果与试验结果吻合较好;嵌贴长度、CFRP板条宽度对于加固效果和破坏模式有重要影响。

| Abstract: | For further research on the behaviour of RC beams flexurally strengthened with NSM FRP strips,a finite element model is established based on the 14 specimens of existing experiment.The results such as ultimate loads and load-deflection behaviour agree well with the experiment;embedment length and strips width have great influence on strengthening effect and failure mode. |
