A structural steel column base plate plan features four anchor rods and symmetric positioning, accompanied by steel joist bearing connections at panels and columns. The joist seats bear upon structural supports with specific vertical clearances, including a two-and-a-half-inch space to the bottom of roof plywood sheathing. Notes direct the user to the steel column schedule for base plate dimensions and anchor rod sizing, and reference Table 14-2 of the AISC Steel Construction Manual for maximum anchor rod hole diameters and minimum washer requirements.
