Shear behavior of reinforced concrete beams strengthened by CFRP strips

In this research, twelve normal reinforced concrete beams are used with dimensions of 110Ch10Ch20 cm, the compressive strength for all specimens is 30 MPa. Deformed bars 2Ø12mm with Ø6mm were used for longitudinal reinforcement, while for transverse reinforcement deformed bars with 5cm, 10cm and 15c...
