Structural response of corroded concrete columns with different rebar confinements under cyclic compressive loading
Structural response of corroded concrete columns with different rebar confinements under cyclic compressive loading
The new codes have recently introduced seismic detailing for new structures, but there are still older reinforced concrete structures without proper ductile detailing for earthquake resistance. These structures are further impacted by the corrosion of their embedded rebars which further reduces the strength and ductility under loading. This paper presents summary of the results of an experimental investigation performed on short RC columns, with different confinement configurations subject to varying degrees of corrosion, to investigate the structural responses to cyclic loading. The experiment was conducted on 20 short RC columns (square and circular) with two levels of confinements and steel reinforcement corrosion loss ranging from 0% to to ~30% subjected to cyclic compressive load. The test results show that corrosion and rebar confinements significantly impact the structural responses of corroded columns.

Abstract
The new codes have recently introduced seismic detailing for new structures, but there are still older reinforced concrete structures without proper ductile detailing for earthquake resistance. These structures are further impacted by the corrosion of their embedded rebars which further reduces the strength and ductility under loading. This paper presents summary of the results of an experimental investigation performed on short RC columns, with different confinement configurations subject to varying degrees of corrosion, to investigate the structural responses to cyclic loading. The experiment was conducted on 20 short RC columns (square and circular) with two levels of confinements and steel reinforcement corrosion loss ranging from 0% to to ~30% subjected to cyclic compressive load. The test results show that corrosion and rebar confinements significantly impact the structural responses of corroded columns.
