The seismic response and the failure mode of reinforced concrete structural elements can be significantly affected by the detrimental effects induced by corrosion, as cracking, concrete crushing, size reduction of reinforcement, and degradation of mechanical properties of materials. The aim of this work is to evaluate the influence of corrosion on the structural response of reinforced concrete columns, using finite element analysis. A parametric analysis is conducted in order to investigate the dependency of ultimate chord rotation on the corrosion level of longitudinal reinforcement. Finally, a reductive coefficient, to be applied to the empirical formulation for the calculation of ultimate chord rotation, is proposed.

Abstract
The seismic response and the failure mode of reinforced concrete structural elements can be significantly affected by the detrimental effects induced by corrosion, as cracking, concrete crushing, size reduction of reinforcement, and degradation of mechanical properties of materials. The aim of this work is to evaluate the influence of corrosion on the structural response of reinforced concrete columns, using finite element analysis. A parametric analysis is conducted in order to investigate the dependency of ultimate chord rotation on the corrosion level of longitudinal reinforcement. Finally, a reductive coefficient, to be applied to the empirical formulation for the calculation of ultimate chord rotation, is proposed.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
