Unbalanced Snow Load IBC 2000
Unbalanced Snow Load IBC 2000
(OP)
I am designing roof rafters for a single family residence. If I apply an unbalanced snow load, the rafters in the IBC Residential Code tables do not work. (My model includes a ceiling joist). I can only get the rafters in the table to work with balanced snow loads.
Does anybody know of a stipulation in the Code where you do not have to apply unbalanced snow loads to residential buildings?
Thanks!

You are governed by the IRC. The IBC is a code book whereas I view the IRC as more of a recipe book. I am doing good to stay up with the IBC changes every three years and thus do not profess to know that much about the IRC. Look in the IRC and I expect it says the span tables are OK w/o drifting. IRC R301.2.3.
For what it's worth, I design any rafter and its connections for the drifted snow condition.
