• Abstract:
  Reinforced concrete bridge piers in Texas have ; shown signs of concrete deterioration in the ; form of map cracking within a few years after ; construction. The pattern cracking is associated ; with the deleterious effects of alkali-silica ; reaction (ASR) and delayed ettringite formation ; (DEF) within the concrete over time. The effects ; of premature concrete deterioration caused by ; ASR and/or DEF on the structural performance, ; in particular the end regions of structural ; elements known as disturbed or D-regions, is ; unknown. It is also not known how to take these ; effects into account in a commonly used design ; office analysis technique such as the strut-and-tie (SAT) method.
