摘要
本文基于混凝土结构设计规范中抗弯设计计算的基本原理,通过对粘贴钢板加固钢筋混凝土简支梁的受力分析,提出了其截面延性的计算方法,并讨论了其影响因素。结果表明,后粘钢板用量及其滞后应变是影响混凝土梁加固后延性的主要因素。
This paper based on the fundamental theory of flexural design calculation of code for design of concrete structures, through to bonded the steel plates to reinforce the reinforced concrete simple beam the stress analysis, a calculation method of ductility of section of concrete beam strengthened bv bonded steel plates was presented, and the influencing factors on it were discussedo The results show that the quantity of steel plate and its lagged strain are the most important factors influencing the ductility.
