A structural steel beam supports wood framing through a custom steel plate bucket connection, tying into wood nailers and drag straps. A 3x12 nailer secures with two rows of five-eighth-inch diameter threaded studs spaced at twelve inches on center, totaling eighteen studs with a six-inch minimum end distance and one-inch maximum countersink. Truss or full-depth laminated strand lumber blocking is positioned at the ends and midspan of the beam with four 10d nails to each block. A 2x12 nailer connects with five-eighth-inch diameter threaded studs spaced at four feet on center with a six-inch minimum end distance. Special diaphragm nailing and framing configurations apply per plan at adjacent structural boundaries.
