A wide-flange column and buckling-restrained brace base plate connection bears on a concrete foundation. Two rows of ASTM F1554 Grade 105 headed anchor bolts secure the base plate, featuring a minimum threaded bolt projection of 6 inches and PVC sleeves sized to a maximum of 1/2 inch oversize for the anchor rods. An embedded plate is cast into the foundation with non-shrink grout filling the annular space at the shear anchors. The gusset plate and brace connect via a shear plate with oversize holes and weld washers, utilizing complete joint penetration demand critical welds. Notes require protecting the steel from free water where concrete pours against the gusset and column.
