Debonding and Crack of the R/C Beam Strengthened with CFS

CFS 보강 R/C 보의 균열 및 탈착

This study look into the mechanisms of growth and magnification in the cracks and delamination on the beams repaired with CFS. The experimental parameters was a loading type, loading speed and pre-crack. In the experiments, it was confirmed that the failure of beams began with development and propagation of the delamination in the below the loading point due to magnification of cracks, but it was not concerned with loading type, loading speed and pre-cracks. Particularly, in the case of beams having the pre-cracks, growth of crack concentrated at the special crack below the loading point and led to failure of the beam by delamination due to magnification of crack.
