Cover Story: This paper presents a multi-scale, multi-physics computational framework that models reinforced concrete behavior undergoing coupled alkali–silica reaction, creep, shrinkage and thermal deformations under varying environmental conditions. A physics-based formulation is presented and calibrated using laboratory size samples. The predictive capability of the model is demonstrated by how the simulation of alkali–silica reaction affected reinforced concrete beams. View the paper
