A structural concrete wall anchors a wood floor system using an embedded continuous reinforcing bar and an embedded steel angle secured with three-quarter-inch diameter countersunk stud anchors at sixteen inches on center. A four-by-twelve Douglas Fir number one floor joist at forty-eight inches on center sits in a Simpson hanger, supported by a double floor joist at similar conditions and stiffened by flat blocking underneath. A continuous steel angle and a Simpson CMST12 long strap span the connection, fastened with twenty-eight sixteen-penny nails and connected to the framing with two seven-eighths-inch diameter through-bolts through double two-and-a-half by two by three-eighths-inch leg-vertical angles on each side spaced at forty-eight inches on center. A four-by-four Douglas Fir number one wood nailer sits above with countersunk anchors, and field welds are specified as quarter-inch typical fillets.
