N2 - Past research has shown that in concrete structures, cement with high alkali contents combined with reactive siliceous aggregates can result in Alkali Silica Reactions (ASR) in the presence of sufficient moisture. A gel-like product resulting from ASR can expand and create an expansive pressure in the concrete, leading to cracking of the concrete. For reinforced concrete (RC) structures, this deterioration mechanism may weaken the bond behavior at the steel-concrete interface and possibly the structural capacity. Columns in RC bridges commonly contain a lap splice of the longitudinal reinforcement near the base of the column. In order to accurately assess the column and bridge reliability, it is important to account for the possible effect of ASR on the steel-concrete bond behavior in the lap-splice region.
