The purpose of this study is to investigate the flexural behavior of reinforced concrete members strengthened by E.M.S(Epoxy Mortar including fiber Sheet) panel. The variables are the type of reinforcement(E.M.S panel, carbon fiber sheet), the amount of reinforcement(2, 4, 6 layer of sheets) and the condition of specimen before reinforcing(previous loading or not). Through the test, we examine about failure mode, load-displacement relationship, moment-curvature
relationship, flexural strength, flexural stiffness and ductility with these variables.
The results of this study are as follows : The specimens strengthened with E.M.S panel appeared a good flexural performance and the flexural strength are agree with the values of a previous proposed equation. In other hand, the specimens with CFS reinforcement showed a bond failure at the interface of concrete and CFS before getting the expected strength. Therefore, we could obtain a good flexural performance and the proper bond performance between E.M.S panel and concrete members in E.M.S panel reinforcement through this study.
