Modelling of RC Beams Strengthened with Basalt Reinforced Concrete

An analytical model was developed to predict the response behaviour of RC beam strengthened with basalt reinforced concrete. The model was based on the internal forces, strains, and stresses in the cross- section of the strengthened composite beam. It is observed that the analytical results are in good agreement with experimental results. Further, non linear finite element analyses was carried out on RC beams strengthened with basalt reinforced concrete. Geometric modelling, material modelling and interaction between different materials were discussed in detail. Displacement controlled analyses were performed and the response behaviour was validated by comparing with the respective experimental results. Parametric studies were conducted on RC beams strengthened with basalt reinforced concrete and the effect of volume fraction towards enhancing the flexural behaviour of RC beams was studied in detail.
