Frequently Asked Questions
NDS (2001/2005) Section 5.3.7 describes a specific loading scenario of "loaded parallel to the wide face of laminations" for application of the flat use factor, Cfu, for structural glued laminated timber. Does the flat use factor apply where eccentric column load induces moment in the y-y direction?
Yes, the factor applies to all y-y bending where the member dimension parallel to the wide face of the laminations is less than 12 inches.
