| Résumé: | This paper evaluate the flexural–shear behaviour of reinforced concrete beams
strengthening by embedded carbon fiber reinforced polymer grids (CFRP grids) and
metallic grids with hexagonal meshes, under four-point bending test. An experimental
investigation was carried out to evaluate the performance of this new technical of
strengthening, Three control beams and fifteen beams strengthened in flexural–shear
with different configurations have been tested. Several parameters were considered to
highlight the efficiency of the technical used, such as; ultimate load, ductility and failure
modes. The experimental results show that the beams strengthening by embedded carbon
and metallic grids offered a great improvement in strength, midspan deflection and
ductility index; in effect, an influence directly on the failure mode is observed |
