Fort Hood & Fort Sam Houston - Progressive Collapse Analysis
FORT HOOD & SAN ANTONIO, TX, 2010
Fort Hood & Fort Sam Houston
Location: FORT HOOD & SAN ANTONIO, TX
Performed progressive collapse analyses on two 5-story barracks buildings to be constructed at Ft. Hood and Ft. Sam Houston, TX using the provisions of the United Facilities Criteria (UFC) 4-023-03 “Design of Buildings to Resist Progressive Collapse, July 14, 2009.” The buildings consisted of cold formed steel stud bearing walls, a composite concrete steel deck floor system, and a steel truss roof system. Miscellaneous structural steel beams and columns were also present in open areas of the buildings.
Extreme Loading® for Structures (ELS) software was used to model and analyze the buildings with its 3-D nonlinear dynamic analysis environment. Modeling and analysis helped in determining the potential for progressive collapse in the structure using the Alternate Path Method for removal of specified exterior and interior vertical supports at certain locations and certain floors of the buildings to verify that the structure has adequate flexural resistance to bridge over the missing vertical support.
