Description
» REINFORCED CONCRETE BEAM
» FLEXURAL STRNGTHENING AND COMPRESSION RESTORING TROUGH PRE-TENSIONING OF CARBON PLATES
The problem
- Degradation and deterioration of the beam caused by a change in load conditions or by a degradation of the initial performances of the materials with consequent reduction of the load-bearing capacity, resulting in the shearing off of some pre-stressing strands and in concrete detachment.
The solution
- To reinforce the intrados of the beam by using pultruded carbon fibre plates appropriately pretensioned, in order to provide the beam with the same pre-compression which it lost as a result of the strands cutting of.
