Abstract:
Since its initial publication in 1969, Unified Facilities Criteria (UFC) 3-340-02 (formerly Army Technical Manual 5-1300/Navy Publication NAVFAC-P397/Air Force Manual AFR 88-22) has provided uniquely practical and intuitively straightforward procedures for analyzing and designing blast resistant structures. With its unlimited distribution, UFC 340-02 is the blast design manual of choice of both government explosives safety experts and private A-E firms throughout the world. This paper summarizes updates to the blast design guidance in chapter 4, reinforced concrete design. Detailed data are presented on the revisions in three areas: dynamic increase factor, design of diagonal tension reinforcement in walls and slabs, and prediction of concrete spall and breach. The paper concludes with a brief discussion of future work.
