基于二次受力的粘钢加固RC梁位移延性分析
Displacement Ductility Analysis of RC Beam Strengthened by Bonded Steel Plates Based on the Secondary Stress
摘要
Abstract
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.关键词
