Where can I obtain information on designing post frame structures (sometimes referred to as pole buildings or pole barns)?
1. Design values for poles (smaller at the top and buried) and piles (smaller at the bottom and driven) are in the 2005 NDS Chapter 6. Design values for poles and piles were moved to the NDS Supplement: Design Values for Wood Construction in the 2012 Edition.
2. Post-Frame Design Manual (Second Edition) to be published by the Technical & Research Committee of the National Frame Builders Association (NFBA).
