API 650: Are rafter supported roofs considered self-supporting?
API 650: Are rafter supported roofs considered self-supporting?
(OP)
Should API 650 section V.7.2 be applied if the roof has rafters but no columns? My vote is no, but a senior engineer here says the opposite. Any thoughts or clarification would be appreciated.

either by rafters on girders and columns or by rafters on trusses with or without columns.
