摘要
在对6根碳纤维布加固钢筋混凝土梁试验的基础上,通过对非预应力碳纤维布与预应力碳纤维布加固钢筋混凝土梁的裂缝、挠度及承载力分析比较,得出预应力碳纤维布加固可以更好的改善构件的变形性能,增强构件的变形能力,预应力碳纤维布加固方法可以应用于实际工程中.
Based on the test results of 6 RC beams strengthened with prestressed carbon fiber sheet and with non-prestressed carbon fiber sheet, the shear properties such as the diagonal crack width, the deflection and the shear bearing capacity between such two kinds of beams are discussed and compared with. It is indicated that the shear properties of the beams strengthened with prestressed carbon fiber sheet are obviously improved, and this new strengthened technique can be used in practice.
