About this detail

A wide-flange column and braced frame connection anchors to a reinforced concrete foundation. The assembly includes a base plate secured by ten 1-1/4 inch diameter anchor bolts conforming to ASTM F1554 Grade 55 with plate washers and standard holes, set over a 1-1/2 inch non-shrink grout layer. A T-lug shear key projects below the base plate into a grout pocket within the concrete pier, which is reinforced with a cage of number 5 ties. The wide-flange column and intersecting brace meet at a working point above the base plate, with welds specified at five-sixteenth inches typical on two sides. Additional plans and structural elevations govern the specific brace sizing, forces, and overall framing geometry.
