This is accomplished by providing out of plane stiffness with transverse web stiffeners. The value of the load modifier, ηi (see AASHTO LRFD Article 1. design bolted connection of the bracing to girder to prevent 10. The plate girders are typically I-beams comprised from separate structural steel plates (rather than rolled as an individual cross-section), which can be welded or, in older bridges, bolted or riveted together to create the vertical web and horizontal flanges of the beam. These can be accomplished by design optimisation. …We're going to take a look at a few other settings…we've never looked at with our pre-cast. proper weld start and termination. Folded Steel Plate Girders What is a folded steel plate girder (FSPG)?
