Project Details:

• 240 ft. (73.1m) clear span precast segmental folded plate arch roof structure,
• 60 ft. (18.3m) clear height at the crown

Hangar was required to accommodate two B-2 Bombers (“Stealth” Bombers). The Hangar is completely air-conditioned.

Challenge:

Design to resist seismic Zone 4 earthquake load and 170 MPH wind load To minimize on-site casting work, speed construction and use least amount of material (concrete and rebar)

Results:

From past experience 55% savings in concrete and 40% savings in rebar are achieved using the precast folded plate roof system in comparison with conventional design using cast-in-situ concrete. Total Construction Cost: US$32.8 million (completed in 2005)
