摘要
进行了 5根碳纤维布加固钢筋混凝土梁的抗弯试验 ,重点研究了碳纤维U形箍的位置、数量及间距等方面对纵向碳纤维布锚固性能的影响。研究结果表明 ,碳纤维U形箍能够较好地减少碳纤维发生剥离破坏的可能性 ,其对纵向碳纤维应力分布的影响不大。碳纤维U形箍的宽度不宜小于 15cm ,不宜少于 2道 ,间距不宜大于 2 0cm。
Bending resistance tests of five RC beams strengthened with carbon fiber sheet (CFS) were carried with the emphasis on the effects of position,quantity and space etc of U hoop of CFS on the anchorage property of longitudinal CFS.The research result shows that the U shape hoop of CFS can reduce the possibility of longitudinal CFS peeling damage,and the influence of it on the longitudinal stress distribution of CFS is not large.
