This structural assembly consists of hollow structural section columns intersecting wide-flange beams with typical quarter-inch fillet welds. The HSS6x6 columns feature quarter-inch cap plates typically and are tied into the W18 framing using L6x6x5/16 angle clips measuring zero feet six inches on each side and end. Three-quarter-inch diameter through bolts with damaged threads after placement secure the connection through long slotted holes, maintaining a maximum three-quarter-inch gap. Base connections are referenced to sheet S502.
