Rational load rating of deck-girder bridges with girder end shear cracks in reverse orientation
… at the supports of many reinforced concrete girders is a phenomenon affecting a number of KDOT’s low-volume bridges built in the early-to-mid 1900’s. This phenomenon is not addressed in the AASHTO Bridge Design Manual (2002) or ACI specifications. This study investigates the causes of this …

Performance and Design of Anchorage Zones for Post-Tensioned Box Girder Bridges
Post-tensioned box girder bridges are very common form of bridge construction. The post-tensioning anchorage zone is the location where very large prestressing forces are applied to the box girder, and then spread into the box section. The spreading of the large compressive forces creates …

Rehabilitation of concrete girders with distressed end regions using innovative materials
… Among all types of damage, the distressing of end regions in bridge girders is very commonly observed. This damage could be in the form of cracking and spalling of concrete and steel corrosion. This research focuses on addressing this type of damage through innovative repair methods using two …
