ALKALI-AGGREGATE REACTION STRUCTURAL EFFECTS: A FINITE ELEMENT MODEL

In reinforced concrete members or structures, alkali-aggregate reaction causes expansion. This expansion is bound in the structure, first by the reinforcement bars and second by the cohesion between the deteriorated layer and the non affected deeper layers. These bounds increase internal stresses and create cracks in the structure. In this paper, a new numerical approach to evaluate stresses, strains and displacements generated by alkali-aggregate reaction is presented. This approach is then applied to a case study to determine the distribution of efforts generated by the expansion. (A) For the covering abstract see IRRD 871351.
