DESIGN REQUIREMENTS
1.2.1
Door Design
[The hangar doors shall be designed by the manufacturer in accordance with
the criteria specified.]
Doors shall operate without binding,
interference, or damage to weatherstripping. Doors shall fit closely and
be free from warping.
1.2.2
Steel Design
AISC 335, AISI SG-973.
1.2.3
Loading
Design doors as a system to withstand an external wind load of one
kilopascal 20 pounds per square foot (psf) or the design wind load
indicated for the building, whichever is greater, and an internal wind load
of not less than one-half of the external wind load. In both cases, the
deflection shall not exceed the height of the door divided by 120. The
deflection due to design wind load shall not exceed length divided by 120
for any door member. Fiber stresses due to combined dead load and wind
load shall not exceed the recommended design stresses for the material used
and type of loading sustained.
1.2.3.1
Deflection
Design doors as a system to withstand the upward and downward deflections
of the cantilevered structure supporting and bracing the top of the hangar
