Featured Project

 

Structural Characteristics:

Hangar Building 340 is a conventionally reinforced cast-in-place concrete structure that was constructed by the Navy in 1940, for use by large seaplanes.

 

The structure consists of a double arch type of construction having overall dimensions of 250 feet by 600 feet with a maximum height of 80 feet at the crown of the arches. Clear span of arches is almost 300 feet.

 

Structural Characteristics

The load carrying system consists of thin shell concrete roof slab supported by reinforced concrete arches. The thin shell concrete roof has a thickness of 4-6 inches. The concrete arches have a depth of 6 feet at their crown and 14 feet at their base, with widths varying from 2 to 7 feet. Both the thin shell concrete roof slabs and the concrete arches are heavily reinforced with both plain and deformed reinforcing bars.

 

Due to the uniqueness of the framing system coupled with its massive size and very long clear span of almost 300 feet, Hangar Building 340 is recognized by the American Society of Civil Engineers as a Historic Building.

 

At the present time, this hangar is utilized by the Navy for housing four squadrons of helicopter craft, with a total staff of about 1,000 Navy personnel assigned to this maintenance hangar that is considered an essential facility.
