A 3-ply with 2 X 10s would mean that three 2 X 10s are ... The distance your joists can safely cantilever or overhang a drop beam is determined by the size of the joists, the wood type and grade of the lumber and the spacing between joists. Many building departments limit joist cantilevers to 24" maximum. Generally, you should use at least five framing nails to attach the rim joist to the ends of your ...The 1.15 or 15% ‘Repetitive Member Factor’ (Cr) recognizes that the built-up beam, predictably, is stronger than timber of comparable dimensions, and is usually factored into span tables. The bottom line then is that although a 6×6 beam is 22% larger than a triple 2×6 beam of the same length, the ‘Repetitive Member Factor’ of 15% decreases the …Example: A deck with a beam located 12 ft. 6 in. from the ledger, framed with 2×10 joists at 16 in. on center.
