REINFORCED CONCRETE BEAM Flexural strengthening with carbon fibre plat
» FLEXURAL STRENGTHENING WITH CARBON FIBRE PLATES
- The beam has deficiencies in longitudinal flexural reinforcement caused by a change in load conditions or by a degradation of the initial performances of the materials.
- The longitudinal reinforcement may be supplemented by the use of pultruded carbon fibre plates, with fibres placed parallel to the axis of the beam, and directly bonded to the restored intrados of the beam itself. This intervention is particularly useful when the reinforcement quantity becomes substantial, and when the concrete surface is already very smooth (precast beams).
