Shear performance of ASR/DEF damaged prestressed concrete trapezoidal box bridge girders

Shear performance of ASR/DEF damaged prestressed concrete trapezoidal box bridge girders

Concrete bridges in Texas have developed large cracks in bent caps and pretensioned trapezoidal bridge girders. The bridges show premature concrete deterioration due to alkali-silica reaction (ASR) and delayed ettringite formation (DEF). There is concern that deterioration due to ASR/DEF may lead to...
