Shear strengthening of reinforced concrete beams with CFRP

The shear strength of FRP strengthened beams is usually calculated by adding individual components of shear resistance from the concrete, steel stirrups and FRP. The superposition method of design is replaced in Eurocode 2 by the variable angle truss model in which all the shear is assumed to be resisted by the truss mechanism.

PDF] Shear Strengthening of Reinforced Concrete Beams

This project presents the outcome of an experimental program aimed to investigate the shear behaviour of externally plated reinforced concrete beams. A total of four beams were tested in this program. The beams were designed to fail in shear. Then, they were strengthened using various configurations of steel plates and angles which have been connected by the weld and bonded to the beams by
