Patch loading or partially distributed load is a special load case in which plate and
box girders are subjected to localized compressive edge loads in the plane of the web. This
load case is present in many applications, including beam-beam and beam-column connections
as well as deep crane runway beams loaded by crane wheels. The most realistic load case is
during the incremental launching of multi-span steel and composite bridges over temporary or
permanent supports. In all these applications, plate girders are frequently supported at crosssections where no vertical web stiffener exists, and the load is transferred into the web panel
through the loaded flange. By using longitudinal stiffeners for flexural and shear strength, the
patch loading resistance can be increased as well. However, scarce work has been found in
the literature for the influence of patch load length on the ultimate strength of longitudinally
stiffened steel plate girders...
