About this detail

Gravity column base plates are welded to wide-flange and hollow structural steel columns using specified fillet welds and secured with four anchor bolts. For wide-flange columns such as W10x, W12x, and W14x, plate thicknesses range from 1-1/4 inches to 2 inches with bolt spacings from 7-1/2 inches to 10 inches, connected with five-sixteenths inch typical fillet welds. Hollow structural section columns like HSS6x6, HSS8x8, and HSS10x10 utilize plate thicknesses from three-quarters of an inch to 1 inch with bolt spacings from 5 inches to 7 inches, connected with quarter-inch typical fillet welds. Anchor bolt locations are dimensioned with two-inch edge distances from the plate edges.
