Flexural Behavior of Damaged RC Beams Repaired with Epoxy Mortar System

에폭시 모르터로 보수한 손상을 입은 RC 보의 휨 거동

This paper presents an experimental study on flexural behavior of damaged RC beams repaired with epoxy mortar system. The main test variables are repair length and depth. A series of 7 specimens was tested to show the corresponding effect of each variables on maximum load capacity, load-deflection relationship, and failure mode. The results of this study shows that flexural behavior of repaired RC beams changes as the repair length and depth is getting longer and deeper, so that the tension strength of repairing materials should be considered in the courses of repair design.
