In the 1997 UBC elements and components are designed using a wind loading
based on a uniform loading calculated from the mean roof height. (Section
1622). On the other hand, primary frames and systems (method 2) uses a
stepped loading going up the building (Section 1621).
Since the load path is from the exterior elements to the primary frame, why
isn't primary frame subjected to and designed for the same wind loading as
the exterior elements?
