DESIGN TYPES

BASIC DESIGN DEFINED BY THEORY OF
OPERATION

THREE PRIMARY TYPES AVAILABLE
 BEAM
 TENSION
 COMBINATION

VARIOUS DOOR CONFIGURATIONS
AVAILABLE USING ONE OF THE ABOVE
TYPES
DOOR TYPES
Beam Type (LPD 17): stiff
in wind, thick and heavy,
significant drive system
impact
Tension Type (WAGB 20
HANGAR): light, thin &
flexible, deflection limited
Combination (CPF): acts as
beam type in normal loads,
acts as tension type for
high loads
LOADS & REACTIONS
Stiff, small deflection
under high loads, no end
in plane end restraint
Flexible, large deflection
under load, panel in
tension
Stiff at small loads and
flexible at high loads
