Reinforcement corrosion can induce sev- ere damage in reinforced concrete (RC) columns leading to a relevant loss of bearing capacity. This condition can be even more critical in case of seismic events. The possibility of repairing and strengthening corrosion damaged columns with high performance fiber RC (HPFRC) jacketing is investigated herein. The main aim of the retrofit intervention is, not only to restore the original bearing capacity, but also to increase the column durability. In order to investigate the effectiveness of the proposed technique, full-scale tests on RC columns under cyclic loads have been performed. Two columns were artificially corroded and one of them was repaired with a HPFRC jacket. The obtained results are compared with those mea- sured on a third un-corroded RC column.

Abstract

Reinforcement corrosion can induce sev- ere damage in reinforced concrete (RC) columns leading to a relevant loss of bearing capacity. This condition can be even more critical in case of seismic events. The possibility of repairing and strengthening corrosion damaged columns with high performance fiber RC (HPFRC) jacketing is investigated herein. The main aim of the retrofit intervention is, not only to restore the original bearing capacity, but also to increase the column durability. In order to investigate the effectiveness of the proposed technique, full-scale tests on RC columns under cyclic loads have been performed. Two columns were artificially corroded and one of them was repaired with a HPFRC jacket. The obtained results are compared with those mea- sured on a third un-corroded RC column.
