Typical base plate layouts for wide-flange and hollow structural section columns feature anchor bolt spacing dimensions and fillet weld specifications. The wide-flange column base plate detail features five-sixteenth-inch typical fillet welds around the perimeter of the flanges and web, with anchor bolts positioned at each corner according to specified edge distances and bolt spacings "S". The hollow structural section column base plate detail employs one-quarter-inch typical fillet welds around the square tube profile with corresponding corner anchor bolts. A schedule correlates column sizes including HSS8x8, HSS10x10, W10x, W12x, and W14x with their respective base plate thicknesses "t" ranging from one inch to two inches and bolt spacings "S" from six inches to ten inches.
