About this detail

An HSS6x3/8 structural steel column post connects to a steel beam overhead using a top plate and bottom connection assembly. The connection features a PL1x10x1'-0" A36 plate secured with two 7/8-inch diameter A325 bolts per flange at AISC gauge, accompanied by a 3/8-inch plate on the near side and far side. A 3/4-inch base plate with eight 3/4-inch diameter by 6-inch lag screws anchors the base of the HSS column. Fillet welds of 1/4-inch and 3/8-inch sizes along with a complete joint penetration weld at the top and bottom tie the members together. Section notes dictate allowable stress design loads including 7,000 pounds dead load, 2,500 pounds seismic load, and 2,800 pounds snow load applied to the DLT.
