Title: Calculating Fire Ratings



Now is it possible then to design a 1-hr Type V building with exposed timbers sized according to UBC standard 7-7?

Volume 3, Standard 7-7 section 7.729 for wood.

That procedure has it's basis in a mechanics-based approach as outlined on Technical Report 10 Calculating the Fire Resistance of Exposed Wood Members, which is available at the following link:

Does anybody know exactly where in the 1997 UBC it allows you to
calculate the fire resistance of an exposed structural member such as a
glulam or steel beam?
