Abstract
The purpose of this study is to investigate shear strengthening effects and behaviour of RC beams strengthened in shear by Carbon Fiber Mesh(CFM) and mortar for fixing CFM to concrete. Test parameters in experiment are shear span-to-depth ratio, layout of CFM and number of clip. From the test, it was shown that the governing failure patten was the bond failure between cover mortar and RC beam initiated at about 60% of maximum strength. And the strength of CFM was developed up to 19.6% of it's maximum tensile strength when the specimen reached to failure. The most effective enhancement using CFM and mortar were to attach CFM diagonally to concrete in a/d of 1.0 and increase the number of cilps in a/d of 1.5, respectively.
