My understanding is that the prescriptive span lengths presented in the Table are for beams that are supported on one side, not that there is a restriction on supporting joists on both sides of the beam.  If you have joists on both sides of the beam, you would double the joist spans in the table to read the maximum beam span.  If your joist spans are greater than 9', you will have to design the beam per the NDS.

So if I am reading this correctly deck beams can now only support joists from one side?  Anyone have any idea of the reasoning behind this?   Thanks in advance
