Abstract:

A steel girder twin bridge structure located near Park City, Kansas, has experienced ; extensive distortion-induced fatigue cracking in its web-gap regions. Due to ; the bridge’s skewed, staggered configuration, the majority of these cracks have ; occurred in the bottom web-gap region. The bridge was previously the subject of ; a series of detailed finite element analyses that investigated the effectiveness of ; several types of retrofits in repairing its distortion-induced fatigue cracks. One of ; these retrofits, the “angles-with-plate” retrofit, was developed and tested at the ; University of Kansas as a new retrofitting technique aimed at providing a more ; economical and easy-to-install distortion-induced fatigue cracking repair. The ; retrofit is made up of a pair of angles and a backing plate that connect the crossframe ; connection plate and girder web in order to stiffen the web-gap region. ; Results from the finite element analyses determined that the angles-with-plate ; retrofit was the most effective and economical choice for repairs in the bridge, ; and plans were made for its installation.
