Abstract
The main objective of this study is to predict the flexural and the shear response of light weight beams designed by embedded triangular FRP/Polymer member under cyclic loading. A local approach based on 3D finite element modeling is carried out to assess the most adequate parameters influencing the ultimate behavior of the new beam and also to evaluate the contribution of the FRP-Jacket comparing to conventional reinforced concrete beams. Concrete is modeled according to a damageable elastic-plastic model, which makes it possible to visualize the damages evolution at the local level and to determine the ultimate response and failure mechanism of the simulated beams. However, an elastic-orthotropic model is used to describe the FRP/Polymer behavior. Results comparison in terms of damage, stress, deformation and stiffness recovery highlight the performances of the FRP-Concrete beam.
