Ledger angles are supported by structural steel wide-flange beams at varying vertical alignments. Detail A features a ledger angle positioned above the beam top of steel, requiring a one-quarter-inch thick gusset plate spaced at forty-eight inches on center when dimension A is less than one inch, connected with three-sixteenth-inch fillet welds on two sides. Detail B employs a ledger angle positioned six inches or less below the beam top of steel, utilizing a one-quarter-inch thick gusset plate spaced at forty-eight inches on center when the top flange thickness is one-half inch or less. Details C and D incorporate ledger angles positioned six inches or greater below the beam top of steel, welded with three-sixteenth-inch fillet welds at twelve inches on center. Steel deck and concrete fill are omitted for clarity.
