Metal Building Sheathing Values
Metal Building Sheathing Values
(OP)
I've done quite s few metal building foundation designs but haven't really put much thought into the wall and roof diaphragms.
How do they justify the sheathing with purlins and girts at 4ft on center. I have never been able to find values for this. Maybe I'm not looking in the right spot.

I like to debate structural engineering theory -- a lot. If I challenge you on something, know that I'm doing so because I respect your opinion enough to either change it or adopt it.

You have to remember a few things about metal buildings, the rigid frames are used as part of the LFRS. End wall bracing is typically used to resist lateral loads that accumulate in the last 1/2 bay only. In the other direction, you will typically see side wall bracing. From what I can recall, the manufacturers use horizontal roof bracing the distribute the lateral loads to the side wall.
