This report contains a prescriptive design analysis and a performance based design analysis for a newly constructed United States Air Force 3-Bay Aircraft General Maintenance Hangar and support spaces.

The prescriptive design analysis reviews the code requirements for fire suppression, fire alarm, life safety, and structural fire protection. Additionally, the hydraulic demands of the fire suppression system, and the voltage drop and power supply requirements of the fire alarm systems were calculated. The results of the analysis portray a compliant prescriptive design of the fire protection systems.

The performance based design analysis evaluates the hazards in the 3-bay facility for two objectives; Life safety and aircraft protection. The life safety objective has been evaluated through an analysis of the available safe egress time (ASET) versus the required safe egress time (RSET). The ASET tenability limits for this analysis were defined as when the smoke layer would descend to 6 ft above finished floor. For this scenario, RSET was determined to be 63% less than ASET.

The aircraft protection objective was evaluated by modeling the effects of the design fire on the aircraft against the known critical heat fluxes of the aircraft coatings. Results from this analysis conclude that the performance criteria of the fire suppression systems fail to adequately protect the aircraft from the effects of prolonged exposure to incidental radiant heat fluxes for conservative underwing fires.
