Beam Span between Posts or Ledgers. The trusses I am sitting on them are a 20' span and are constructed from 2x8s as well on a 4/12 pitch. There is a 2x12 as a skirt and its nailed to the 2x8's but it is not bearing on posts. This beam has two spans that are equal and a 220lb concentrated load, which is located at the center of one span. Allowable deflection = 192 in. The numbers in gray indicate the distance between the support posts. or 2x12s at 24” O. 5(1) and Table R502.
