摘　　要：粘贴钢板加固法已经广泛运用于混凝土梁的二次加固设计中。某工业建筑现因工艺变化需进行二次改造,这将导致原有钢筋混凝土梁因承载力不足出现正截面和斜截面两种破坏。针对这两种破坏类型,分别阐述了粘贴钢板加固法的设计原理,从而表明粘贴钢板加固法在二次改造工程设计中是一种行之有效且简单易行的方法。Bonding steel plate reinforcement method has been widely used in the design of two times of concrete beams.An industrial building is due to technological change needs two times of transformation,which will lead to the original reinforced concrete beams due to insufficient bearing capacity there are inclined section and two kinds of failure.According to the two types of failure,this paper describes the design principle of reinforcement plate,which showed that the reinforcement method of bonding steel plate in the two transformation projects the design is a simple and effective method.
