Finite element modeling of RC deep beams strengthened in shear with CFRP strips

摘要

1. The results of this study indicate that the externally bonded CFRP strips can be successfully employed to enhance the shear capacity of the deep beams. 2. When compared with non-strengthened one-point loading beam, load carrying capacity of beam strengthened with 45 degree oriented CFRP strips is enhanced by 51.5%. 3. Similarly in two-point loading beam, load carrying capacity enhances up to 39.8% in 45 degree orientation of CFRP strips in comparison to non-strengthened beam. 4. For one-point load beam, load carrying capacity of 0 degree, 90 degree and 45 degree orientation of CFRP strips show an increase up to 4%, 44% and 51.5% respectively as compared to non-strengthened beam. 5. Similarly in two-point load beam, load carrying capacities of 0 degree, 90 degree and 45 degree orientation of CFRP strips, are observed to increase up to 28.9%, 30.2% and 39.8% respectively compared to non-strengthened two-point load beam.
