Abstract
This paper consists of two experiments to investigate bond behavior for repair and strengthening ofconcrete members, one concrete with fiber sheet in uni-axial tensile test, the other bond fiber sheet to RC member test with notch which limited location of shear crack. Uni-axial tensile test was carried out to change three parameters which were kind of fiber sheet (aramid fiber and carbon fiber), compressive strength of concrete and bond length of fiber sheet. RC member test was carried out to change one parameter which was kind of fiber sheet. The results of this experiments are that bond strength equation between concrete and fiber sheet to include compressive strength and bond length of sheet in uni-axial tensile test and effective bond area in RC members test were obtained. Therefore it was almost possible to estimate bond strength of RC members with fiber sheet due to bond strength equation and effective bond area.
