About this detail

This structural steel bridge base plate connection features a two-inch thick plate supporting a column and brace sized per plan. The upper plate includes machine-scribed alignment lines one-sixteenth of an inch wide by one-thirty-second of an inch deep, centered on the grid lines in three locations. Three thirteenth-sixteenth by six-inch slotted holes accommodate movement, while five-sixteenth inch fillet welds attach the structural members with finishes to bear. Gusset plates and braces connect symmetrically across the assembly per structural drawings.
