Abstract—In present RC beams initially stressed to a prefixed percentage of the ultimate load are retrofitted with ferrocement to improve the performance of RC beam in both shear and flexure, the welded wire mesh is wrapped around the beam in U shape. An experimental work is conducted to evaluate the performance of RC beam retrofitted with ferrocement. In experimental work total 25 beams are casted, from that three beams are control beams. Six beams are shear deficient beam and retrofitted with single and double layer of wire mesh at 00 and 450 orientation. Remaining sixteen beams are distressed at 60%, 80% of ultimate load and retrofitted with ferrocement in number of layers at various orientation. Such distressed beams are divided in four groups. In one group distressed beams are retrofitted with single layer of wire mesh at 00.In another three group retrofitting are worked out with single layer of wire mesh at 450, double layers of wire mesh at 00, double layers of wire mesh at 450, respectively. The load deflection characteristics and mode of failure are studied. The test results indicate that, when beam retrofitted with wire mesh in layers at orientations, it significantly increases the load carrying capacity, first crack load, stiffness but deflection is decreases in both flexural and shear strengthening.
