Columns in reinforced concrete (RC) bridges commonly contain a lap splice of the longitudinal reinforcement near the base of the column. It is important to ensure that the bond within this splice is of magnitude to transfer internal forces so that the column can resist the applied lateral load. However, deterioration mechanisms, such as alkali silica reaction (ASR) may weaken the bond between the reinforcement and the concrete in this lap-splice region, which may subsequently lead to changes in the flexural capacity and demand of the column, which could result in a reduction in the bridge reliability. This paper develops a finite element (FE) model of a RC column subjected to ASR, such that the effects of ASR on column performance and reliability can be quantified. The FE model is built using Abaqus software and the bond-slip relation between the concrete and the reinforcing steel is modeled explicitly. The FE model and in particular the bondslip model are calibrated using the force-displacement data obtained from the destructive testing of eight large-scale column specimens with different levels of ASR deterioration.
