Exterior walls to <br /> have 2x6 studs at 16" on center. Wood joists shall bear the full width of supporting members (stud wall, <br /> beams, etc.) unless otherwise noted. Wood beams made of 2 or more 2x's shall be bolted together with <br /> 3/8" diameter through bolts at 2'-0" on center or equivalent spikes. Sill plates to be bolted to foundation <br /> walls with %" diameter anchor bolts at 4'-0" on center maximum to extend 15" minimum into grouted <br /> masonry. Each sill plate to have a minimum of 2 bolts with one bolt located within 12" of each end of <br /> each piece. Nailing to be in accordance with Table 2304.9.1 of the I.B.C. <br /> LVL WOOD MEMBERS <br /> LVL members noted on drawings are laminated veneer lumber as manufactured by the Trus-Joist <br /> MacMillan.
