Abstract: Abaqus finite element program is employed to analyze the ultimate load capacities of square reinforced concrete plates strengthened by fiber-reinforced plastics. Appropriate constitutive models are introduced and validated to stimulate nonlinear material behavior of reinforced concrete and fiber-reinforced plastics. The influences of FRP reinforcement, steel reinforcement, and concrete properties on the ultimate strengths of the reinforced concrete plates are investigated. Finally, based on the numerical results, empirical equations are proposed to predict increment of ultimate load capacities of the square reinforced concrete plates strengthened by fiber-reinforced plastics, which would be useful for practical engineering applications.
