About this detail

Structural connection assembly at a wood truss bottom chord supporting existing and new joists. Simpson MSTI48 straps center on the existing truss bottom chord above and below, aligned over wall tie joists as indicated in the plan. A four-by wood blocking member is secured with four six-inch structural wood screws, ripped to fit and notched as required at the existing angle hanger. A three-by-four shim, ripped to fit the full length of the joist, is provided at the straps alongside continuous plate members per typical chord details. Existing and new joists are fastened with sixteen-penny nails at six inches on center, supplemented by Laminated Veneer Lumber top and bottom straps.
