Any ideas as how to support the stair treads for this load besides ...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 closest thing would be for the joist span to be 18', which shows the double 2x12 span can only be 6'-9" There is no chart.

The 2015 IRC simplified sizing deck beams with the introduction of Table R507.6 “Deck Beam Span Length.” That table presented the maximum spans for a series of multi-ply, built-up-dimensional-lumber beams from a double 2x6 through a triple 2x12, with beam spans based on the span of the deck joists from the ledger to the beam.1. Table is based on continuous floor joist span and simple or continuous beam span con-ditions. If floor joists are not continuous above the beam, take the sum of the joist spans then multiply by 0.8. This is the total floor joist span to consider. 2. Required end bearing length (based on 565 psi) is 3.0! unless the subscript + is shown.9.23.4.2. Spans for joists, Rafters and Beams.
