Analysis and Design of Beams Reinforced with Steel Fiber and Composite Plates


The addition of epoxy bending plate to the tension and compression facesor web is an effective technique for flexural or shear strengthening ofreinforced concrete beams, also using of steel fibers with concreteimproves the structural behavior and increases the moment capacity andshear resistance of the beams. General equations are derived forpredicting the bending moment capacity, maximum and balancingreinforcement ratio the equivalent depth of the compression zone for singlyand doubly reinforced rectangular sections and T-beams. The resultsindicate that bending moment capacity increased in beams with steel fibersand composite plates, while the maximum balancing reinforcement ratiosare decreased
