Although, I am starting to believe that the NDS modulus of
elasticity numbers are high. I am seeing in the field, members that are
deflecting signifcantly more than they should.
I'm glad I'm not the only one questioning those number; they seem a
little high.
Maybe the "poor" deflect behavior is due to lower grade timbers being
wrongly upgraded? Modulus is a strong function (at least I was told)
of density (ring spacing), maybe the currecnt timber is just grown too
fast?
