Improved Cross-Frame Analysis and Design: Wide-Flange T-Shape Sections
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.
