在实体破坏性试验的基础上对部分预应力混凝土T梁粘贴碳纤维加固进行了研究。通过对其进行加载试验,观测其在试验荷载下主梁的变形情况及最终的破坏形态,为进行粘贴碳纤维加固及对单梁承载力与刚度的改善评定提供了参考。 Based on the physical destructive test, the carbon fiber reinforcement of partially prestressed concrete T beam was studied. Through the loading test, the deformation of the main girder under the test load and the final failure mode were observed, which provided a reference for the reinforcement of the bonded carbon fiber and the improvement of the bearing capacity and rigidity of the single girder.
