Re: IBC 2000 Wind Design

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I believe this load combination should be applied to members that are
receiving load from more than one level.  I agree with Roger on this
one.  It doesn't make sense to put a roof live load on at the same time
as a 70 mph wind.  A snow load on the other hand should be used.
