The use of carbon fiber reinforced polymer (CFRP) as an effective approach for
strengthening reinforced concrete members has developed extensively in recent years.
The present study investigates the shear behaviour, including the load-carrying capacity
and mode of failure, of reinforced concrete corbels strengthene d with CFRP fabrics. The
experimental program consisted of five full-scale concrete corb els subjected to a patch
load with a shear span to depth ratio equal to 0.8. The specime ns were designed to fail
in shear. Test results indicated that strengthening of RC corbels with CFRP slightly
enhanced the shear behaviour of the test specimens. The enhance ment in the load-carrying capacity in shear ranged from 7% to 13%. The results w ere compared with
NLFEA predictions which their predictions were conservative |
