Abstract
Here a numerical model is presented that enables simulation of the nonlinear flexural response of RC components with corroded reinforcement. The model employs the force-based beam-column element and the fibre-type section model that are available in OpenSees. A new constitutive model for corroded reinforcing steel is used. This model simulates the buckling of longitudinal reinforcement under cyclic loading and the impact of corrosion on buckling strength. The basic buckling steel model is validated through comparison of simulated and observed response for RC columns with uncorroded reinforcement. Typical concrete constitutive models are employed to simulate the response of components with corroded reinforcement; cover concrete strength is adjusted to account for corrosion induced damage and core concrete strength and ductility adjusted to account for corrosion induced damage to transverse reinforcement.
