Record URL: Availability: Transportation Research Board Business Office 500 Fifth Street, NW Find a library where document is available Abstract: Before 1985, it was common practice to avoid welding floor beam and diaphragm connection plates to the tension flange of steel bridge girders. This practice often resulted in web-gap cracking due to out-of-place distortion of the girder web. The most widely applicable and accepted retrofit method is to attach the connection plate rigidly to the flange. There was an investigation of a retrofit option that used a two-part epoxy cured at room temperature to join a small length of 3/4-in.-thick steel angle shape to the tension flange and the connection plate. Field tests conducted on two multiple-girder bridges indicated that significant out-of-plane stress ranges were typically reduced by at least 40% after retrofit. For details that have the potential for web-gap cracking but have not yet exhibited detectable cracks, the 40% reduction in stress range is likely enough to eliminate the possibility of future web-gap cracking effectively.
