These Unified Facilities Criteria (UFC) provide technical guidance for the earthquake resistant (“seismic”) design of new buildings, and nonstructural systems and components in those buildings, for the Department of Defense (DoD), based on an adaptation of the 2015 edition of the International Building Code (2015 IBC) and the structural standard referenced by it: ASCE 7-10 Minimum Design Loads for Buildings and Other Structures \1\with Supplement No. 1 (hereinafter referred simply as ASCE 7-10). Consistent with the 2015 IBC, this UFC also references the 2015 edition of the International Existing Building Code (2015 IEBC) /1/. The criteria further provide limited technical guidance for seismic evaluation and strengthening of existing buildings. This information shall be used by structural engineers to develop design calculations, specifications, plans, and Design-Build Requests for Proposals (RFPs), and it shall serve as the minimum seismic design requirement for DoD buildings.
