Southern Pine Bending Strength
Southern Pine Bending Strength
(OP)
I'm starting to study for the SE exam in October. I don't do a lot of timber design work, so that's my first subject. I'm getting stuck on a simple step in a sample problem. (For anyone who wants to follow along, it's example 4.1 in PPI's 7th edition Timber Design guide.)
Given a select structural southern pine 4x16 beam. What is the value of Fb, prior to any adjustment factors? I read 2850 psi from NDS Table 4B, but the solved example gives 1900 psi. I'm using the 2005 NDS, as specified for the SE exam and in the PPI book.
I found an addendum to the NDS dated March 2013, which revises the value downward from 2850 to 2350 psi. Still no match, although the revised Fc happens to be 1900. (A red herring perhaps?)
