Estudo numérico de vigas de aço com seção I reforçadas à flexão com laminados de fibra de carbono (PRFC)

Abstract

This work uses the Finite Element Method for the development of numerical models to simulate the flexural behavior of steel I-beams strengthened with CFRP laminates. The approach used consists mainly in the predominant use of shell finite elements for the analysis. The simulations allowed considering the influence of the length and thickness of the CFRP laminates in the failure mode and loading capacity of the strengthened beams. The modeling strategy developed had its results validated with the numerical and experimental results from literature. The used strategy was adequate to simulate the behavior of the beams, presenting coherent results when predicting rigidity, load capacity and structural displacements.
