In 2014 Aircraft Support Industries (ASI) was
contracted by Nagaworld Ltd, Cambodia to design and construct a light
Maintenance Hangar under international building standards to meet their unique
operational business model.
The 5-star Hangar Facility was successfully
completed by ASI in 2016 and consists of a multi-story 25m airside frontage x
45m deep FBO building, and a 100m span x 45m deep stressed arch clear span light
maintenance hangar accommodating a fleet of corporate and business jets up to
and including Airbus A320 aircraft.
ASI’s proprietary and unique stressed arch
hangar design is unrivalled in providing the most cost-effective steel
structure for large clear spans. The facility features the vertical lift doors
allowing flexible, fast and well-sealed protection from the weather whilst
providing the ability to fully open the entire hangar span. The facility is
NFPA409 compliant the internationally recognized standard for fire protection of
hangars.
Stressed Arch building system design
The Stressed Arch structure was fabricated in
Ho Chi Minh City, trucked across the border to Phnom Penh, and bolted together
on site, supported at low level by scaffold towers.
ASI Heavy Lift was engaged to carry out the
stress-erection roof lift utilizing their state-of-the-art jacking equipment and
monitoring systems. Following standard lift-off procedure the day before to
clear the structure from the scaffold towers, the full stress-erection was
undertaken within 2 hours on the morning of the 28th September, in front of a
large and captivated audience of VIP’s and other invited guests. The
stress-erected structure was lifted from its at-assembly shape of 110m span x
11m height, to its final erected and curved arch configuration of 100m span x
24m apex height.

Stressed Arch Roof Interior |
Researched and developed since the mid-1980’s,
the Stressed Arch Building System is a patented method for constructing large
clear span buildings utilizing the combined benefits of the steel truss, the
arch, and high strength steel stressing tendons. The construction of a Stressed
Arch building involves a unique erection process in which the steel trussed
frames are assembled close to ground level in a “flat” position. Using the
stressing tendons, the building is “stress-erected” into the final arch shaped
configuration typical of the Stressed Arch building. The erection process
results in a unique set of structurally favorable conditions imposed on certain
members of the Stressed Arch frames, and the building’s overall load carrying
characteristics.

The resulting purpose designed clear span
buildings are suitable for aircraft hangars, bulk storage, warehouses, sports
and recreation facilities and, in fact, anywhere there is a requirement for cost
effective column free covered space. ASI’s website provides further information
and numerous examples of buildings completed, which number upwards of 100
buildings worldwide.
