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.
