Abstract:This paper corresponds to the second part of a work intended to evaluate the design models of reinforced concrete structures strengthened with Carbon Fiber Reinforced Polymers (CFRP). The shear models analyzed correspond to the guidelines ACI 440 and fib-14, as well as more recent formulations, available in the literature. Such models were applied to eight “T” beams strengthened to shear with CFRP composites strips. Different types of carbon fiber composites (sheets and laminates), from different manufacturers, available in the Brazilian market, were applied. The analyses indicate that anchorage mechanism helps increasing load capacity and ductility and that none of the tested analytical models were capable of reproducing satisfactorily the observed behavior of the tested beams.
