About this detail

The steel beam connects to the supporting girder using complete joint penetration welds at the top and bottom flanges, supplemented by bolted web connections. A filler plate sized to match the difference in beam depths plus one-quarter inch is provided at the bottom flange where required, with a width matching the girder flange and length matching the beam flange. A WT section cut from a wide flange beam serves as a stiffener plate on one side, welded on three sides with fillet welds. Fillet welds of one-quarter inch, five-sixteenths inch, and three-sixteenths inch are specified according to the accompanying notes.
