dc.description.abstractA new bar slip model is developed to account for the contribution of reinforcement anchorage slip to thetotal displacement of corroded reinforced concrete (RC) members. An analytical procedure is proposed tomodel the distribution of the reduced bond stress along the corroded steel bar to predict the reinforce-ment slip in the anchorage area. The reinforcement slip is formulated using an existing model and by newgoverning equations defined for different bond regions. The possibility of having an insufficient embed-ment length is also considered, and a corresponding failure criterion is defined. The bar model is validatedby comparing the available data from single bar pullout experiments and an existing bar force-slip model.The proposed column model is implemented using a fiber element model to capture both the monotonicand cyclic behavior of corroded columns. Pseudo-static test data from corroded column specimens areused to validate the proposed column model. Overall, the proposed model captures the slip of a singlecorroded bar reasonably well to accurately simulate the total lateral displacement of columns with cor-rosion damage.
