摘要
针对粘贴钢板加固RC梁的二次受力特性,在混凝土结构设计规范中抗弯设计计算的基本原理基础上,通过对粘贴钢板加固RC梁的受力分析,提出了其位移延性的计算方法,并讨论了其影响因素.分析结果表明,后粘钢板用量及其卸载百分比是影响RC梁加固后延性的主要因素.
Aiming at secondary stress characteristics of the RC beam strengthened by bonded steel plates, based on the fundamental theory of flexural design calculation of code for design of concrete structures, through the stress analysis of the RC beam strengthened by bonded steel plates, this paper presented a calculation method of its displacement ductility. And the influencing factors on it were discussed. The results show that the quantity of steel plate and its unload percentage are the most important factors influencing the ductility.
