A scenario was created where the occupant was changed to the Department of Defense, who required structures to be directly analyzed to resist progressive collapse. The overall goal for this study was to investigate a new and complicated area of structural engineering, while strengthening standard design capabilities.
The Unified Facilities Criteria design code, written by the Department of Defense, will be used to analyze all progressive collapse criteria. All designs will also be checked against the standard ASCE 7 strength and serviceability requirements. The existing two-way concrete slab system was redesigned into a composite steel structural system. This steel stystem was then analyzed using the Tie-Force Method, Alternative Path Method, and Enhanced Local Resistance Method. The linear static approach was used when analyzing the structure for Alternative Path criteria.
