Does the Cq coefficient for elements in areas of discontinuities apply when
you have an open structure? For example, I have an open frame canopy, steel
posts and beams, supporting a metal roof deck. The metal deck cantilevers 4'
at the front. Does the Cq factor (2.3+.5=2.8 for the overhang and 2.3 for the
perimeter) apply in this case, since there are no two surfaces with an
included interior angle, as defined in the UBC? Any EXPERT (no guessing)
