Axial compression capacity of concrete columns reinforced with corrosion-resistant metallic reinforcement

Abstract Axial compression performance of concrete columns reinforced with 2304 solid stainless bars and spirals, carbon steel 316 L clad is examined after the are exposed to severe corrosion. Two groups were investigated: a control group, group submerged in 5.0% by weight chloride solution subjected accelerated A relatively high impressed current density 8.5 μA/mm 2 was used 60 days corrosion tested failure under axial compression. In terms mass loss per unit energy, spirals either or vertical 197% more resistant than steel. Bars made materials developed localized pitting that led degradation cover larger drop columns. However, reached lower displacements corroded column only experience sudden prior reaching its theoretical maximum capacity. capacity both conditions modeled using confinement models produced good agreement experimental results.
