About this detail

A wide flange column rests on a 1-1/2-inch Grade 50 base plate with a 2-inch nonshrink grout pad above the footing, connected to a reinforced concrete footing. Anchorage is provided by six 1-1/2-inch diameter ASTM F1554 Grade 36 anchor rods extending through the footing to a lower anchor plate measuring 1x24x24 inches. The concrete footing is reinforced with number 4 bars spaced at 6 inches on center, with an embed plate and welded rebar assembly. A buckling-restrained brace connects via a gusset plate sized per the manufacturer requirements with a 1-inch clip, supported by concrete infill per typical isolation joint detail 12/S401.
