Wide-flange (WT) sections for steel bridge applications can be used in cross-frames with similar stiffness and fatigue performance as single-angle sections.
NCHRP Research Report 1045: Improved Cross-Frame Analysis and Design: Wide-Flange T-Shape Sections, from TRB's National Cooperative Highway Research Program, details the many functions cross-frames serve throughout the construction and service life of steel I-girder bridges, with a focus on how they provide girder stability and enhance the lateral-torsional buckling resistance of the bridge girders.
