This Unified Facility Criteria (UFC) provides enhanced design requirements for Risk Category V (RC V) structures, national strategic military assets designed and constructed for the Department of Defense (DoD). These technical requirements are based on the 2021 International Building Code (2021 IBC) and the structural standard referenced by the 2021 IBC: ASCE/SEI 7-16 Minimum Design Loads and Associated Criteria for Buildings and Other Structures (hereafter referred to simply as ASCE 7-16).
This UFC must be used for the design and analysis of buildings and other structures assigned to Risk Category V.
RC V encompasses facilities that are considered to be national strategic military assets (see UFC 3-301-01 Table 2-2). Special design and analysis procedures apply to RC V buildings and other structures. Design RC V structures to ensure that their foundations, superstructures and installed mission-essential nonstructural elements remain elastic, and their installed equipment remains operational when subjected to severe environmental loading.
This UFC modifies provisions of the 2021 IBC and ASCE 7-16 for use in analyzing RC V buildings and structures. In cases where a provision in the 2021 IBC or ASCE 7-16 is not modified by this UFC, first apply UFC 3-301-01 and then apply UFC 1-200-01. If neither of these UFC documents modifies the relevant provision, then apply the 2021 IBC and ASCE7-16 directly.
