粘贴碳纤维布加固法

粘贴碳纤维布加固法适用于提高柱轴心受压承载力、斜截面承载力以及位移延性的加固。当轴心受压柱的正截面承载力不足时,可采用沿其全长无间隔地环向连续粘贴碳纤维布的方法(简称环向围束法)进行加固;当柱斜截面受剪承载力不足时,可将碳纤维布的条带粘贴成环形箍,且纤维方向与柱的纵轴线垂直;当柱因延性不足而进行抗震加固时,可采用环向粘贴碳纤维布构成的环向围束作为附加箍筋。当采用碳纤维布环向围束对钢筋混凝土柱进行正截面加固或提高延性的抗震加固时,环向围束的碳纤维布层数,对圆形截面不应少于2层,对正方形和矩形截面柱不应少于三层。环向围束上下层之间的搭接宽度不应小于50mm,纤维布环向截断点的延伸长度不应小于200mm,各条带搭接位置应相互错开。
