Need E - value for 2x8 SYP M23
Need E - value for 2x8 SYP M23
(OP)
Please, I need this urgently for a meeting with a prefab wood truss mfr.
I need to calculate a girder truss deflection by hand today to verify the truss software output.

-FYI
Per 2001 NDS. SYP SS: 2"-4" wide E = 1,800,000 psi
Per 2001 NDS. SYP #2: 2"-4" wide E = 1,600,000 psi
And you obviously know that these values were dramatically decreased recently (by some 30%!!)

Thanks a million. I heard they changed but I didn't know exactly what because I don't have the latest NDS.
This will give more ammo in my conflict with the truss designer, regards my other post.

I have lot of other very serious doubts, however...I just needed to make a list of reasons why I am rejecting their repair, and I had serious doubts as to the accuracy of their truss software.
