Modeling Strategies of Finite Element Simulation of Reinforced Concrete Beams Strengthened with FRP: A Review

Modeling Strategies of Finite Element Simulation of Reinforced Concrete Beams Strengthened with... <jats:p>Fiber-reinforced polymer (FRP) composites do not only possess superior mechanical properties, but can also be easy to tailor, install, and maintain.
