粘贴钢板或其它纤维复合材料,对梁的受拉薄弱区进行补强,是桥梁加固的主要方式之一。粘贴钢板加固一般采用带载加固,其承载力应按两阶段受力构件计算。在基本假设的基础上,针对桥梁构件两阶段受力的特点,对T形截面梁,分析粘贴钢板加固桥梁构件正截面抗弯承载力的计算公式和适用条件,并给出极限状态加固设计的方法和步骤。
Paste steel plate or other fiber composite materials, the tensile strength of the beam to be reinforced, is one of the main ways of strengthening the bridge. Paste steel reinforcement generally used with load-bearing reinforcement, the bearing capacity should be calculated by two-stage force components. Based on the basic assumptions, according to the characteristics of two-stage force of bridge members, the calculation formula and applicable conditions of normal section flexural capacity of bridge members reinforced by bonded steel plate are analyzed for T-section beams, and the design of limit state reinforcement Methods and steps.
