Title: RE: METAL BUILDING DESIGN METHODS

I used to work for Varco Pruden (VP) Buildings.  They use the standard AISC 9th edition
to design their frames, except for the moment connections of the rigid frames.  The
moment connections they use are based on thier own tests.  They calculate stresses at
all of the girt lines and I seem to remember that they also calculate stresses at 6" O.C.,
but only the stresses at the girt lines and other maximum stresses show up on the output
sheets.  They assume the rafters to be continuous beams from eave to eave with pinned
connections at interior columns and rigid connections at the sidewall columns.  I hope this
helps.
