Experimental study of a rehabilitation solution that uses GFRP bars to replace the steel bars of reinforced concrete beams

摘要

The corrosion of the steel reinforcement affects drastically the long-term durability of many reinforced concrete (RC) structures in the world, especially the ones near the sea. When this problem is detected at early stages, it is possible and important to repair the structure in order to restore its safety and avoid future hazards and more expensive interventions. The research work described in this paper is inspired on these cases as it proposes a rehabilitation solution to replace the tension steel reinforcement of a RC beam with GFRP bars, which is a material immune to corrosion.
