Re: Parallel Chord Wood Floor Trusses

I have not read the article yet.  On a floor I/we use l/360 for live load l/360 for live load and Total load.  With typical spacing at 16" oc.  With  no ceiling or Gyp Bd we are always asked to lower deflection requirements to l/240.  We also tend to over state the dead loads.
