Seismic performance of RC bridge piers reinforced through FRCM confinement

Abstract Corrosion of reinforced concrete (RC) structures is one the main issues concerning existing buildings and especially infrastructures. phenomena, that induced mainly by carbonatation high chlorides concentration, can significantly affect performance structures. In particular, seismic be affected. Loss transversal reinforcement in RC elements reduce ductility while corrosion affecting bending reduces lateral load‐bearing capacity elements. To enhance corroded extend service life deteriorated confinement most effective commonly used techniques. This paper investigates deterioration a bridge affected retrofitted through FRCM confinement. Different retrofitting scenarios are combined fragility curves computed for each case. Finally, time‐variant reliability profiles to evaluate best scenario intervention time maximize gains.
