when assessing the fire rating of exterior bearing walls in IBC 2012 for PPD - the exterior bearing wall is rated per 601 (e.g. 2 hours for Type IIIA) and the non-bearing wall is rated per 602 (e.g. 1 hour for Type IIIA at all/any fire separation distance), is that right?
i mean - in the event you need to determine the fire rating of an exterior wall you would either need to assess the structural requirements of the wall based upon the drawings or you would rely on the answers simply not giving you one or the other answer.
does that analysis make sense to any of the “code wonks” (a term i use affectionately).
