Stiffener plate number one is placed on each side with a width matching the flange plate, while stiffener plate number two matches the unhaunched beam flange width. Complete joint penetration welds are specified at the flange plates and stiffener plates as required, with additional fillet welds denoted by standard symbols. A web plate is provided centered on the web, and the beam end incorporates a maximum cope length with a two inch maximum cope depth. Shear studs are spaced at a minimum of one stud per foot along the top flange supporting a metal deck.
