Abstract
A large number of existing RC structures, whether they have been built of concrete
with usual compressive strength or of concrete with high compressive properties,
exhibit non adequate performance in terms of diminished bearing capacity and there
is a need of post strengthening during their service life. This paper presents
numerical analysis of the influence of the compressive strength of the concrete on
the performance of the CFRP strengthened RC beam. Analysis is performed for two
characteristic cases: when the bond between concrete and external reinforcement is
continuous along the length of the beam and when the bond is improper executed
creating discontinuity zone between RC and CFRP plate.
