16. DESIGN DRIVERS l MISSION / OPERATIONAL REQUIREMENTS l CLEAR OPENING - WIDTH & HEIGHT l LOADS - ENVIRONMENTAL, SPECIAL CASES l INSTALLATION & MAINTENANCE RESTRICTIONS l OTHER FACTORS

17. DESIGN TYPES l BASIC DESIGN DEFINED BY THEORY OF OPERATION l THREE PRIMARY TYPES AVAILABLE BEAM TENSION COMBINATION l VARIOUS DOOR CONFIGURATIONS AVAILABLE USING ONE OF THE ABOVE TYPES

18. 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

19. 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 LOADS & REACTIONS

20. TYPICAL DOOR ARRANGEMENTS l TYPE A - ROLLER CURTAIN SLAT l TYPE B - VERTICAL FOLDING PANEL l TYPE C - VERTICAL SLIDING PANEL l TYPE D - VERTICAL SLIDING PANEL (HORIZONTAL STOW) l TYPE E - HORIZONTAL SLIDING PANEL (HORIZONTAL BI-PARTING) l TYPE F - HORIZONTAL SLIDING PANEL (MULTIPLE STOW)

21. ROLLER CURTAIN SLAT (TYPE A) l LIGHT WEIGHT l COMPACT STOW l EASILY SHOCK QUALIFIED l EASILY MAINTAINED l COST EFFECTIVE l INSIDE OR OUTSIDE MOUNT l DEFLECTION LIMITED l SIMPLE OPERATION

22. VERTICAL FOLDING PANEL (TYPE B) l COMPACT STOW l LOW RCS CAPABLE l HIGH WEIGHT l NON-INTERCHANGEABLE PANELS l DIFFICULT TO SHOCK QUALIFY l REQUIRES OVERSIZED DOOR OPENING l COMPLEX DOGGING

23. VERTICAL SLIDING PANEL (TYPE C) l COMPACT STOW l LIGHT WEIGHT l EASILY SHOCK QUALIFIED l INTERCHANGEABLE PANELS l EASILY MAINTAINED l LOW RCS CAPABLE l COMPLEX DOGGING

24. VERTICAL SLIDING PANEL (TYPE D) l OVER CENTER SELF LOCKING l LIGHT WEIGHT l EASILY SHOCK QUALIFIED l INTERCHANGEABLE PANELS l LOW RCS CAPABLE l OVERHEAD SPACE REQUIRED

25. HORIZ. SLIDING PANEL (BI-PART) (TYPE E) l LIGHT WEIGHT l SELF BALANCING l INTERCHANGEABLE PANELS l SPANS LARGE WIDTHS l EASILY MAINTAINED l EASILY SHOCK QUALD l SIDE SPACE & DECK GUIDE REQUIRED l NO RCS SLOPE

26. HORIZ. SLIDING PANEL (ALT) (TYPE F) l LIGHT WEIGHT l SPANS LARGE WIDTHS l EASILY MAINTAINED l EASILY SHOCK QUALD l SIDE SPACE & DECK GUIDE REQUIRED

27. DOOR ADAPTATIONS AND SPECIAL CONSIDERATIONS l DOOR DOGGING SYSTEMS l DRIVE SYSTEM OPTIONS - ELECTRIC vs. PNEUMATIC vs. HYDRAULIC l COUNTERBALANCE vs. NON-COUNTERBALANCE l SPANNING LARGE OPENINGS

28. DRIVE SYSTEM OPTIONS l FOUR CATEGORIES ELECTRIC PNEUMATIC HYDRAULIC MANUAL l CAN BE CONFIGURED FOR PRIMARY SYSTEMS SECONDARY SYSTEMS AND EMERGENCY SYSTEMS

29. DOOR COUNTERBALANCING l CAN BE FITTED TO MOST DOOR TYPES l COUNTERBALANCES CAN REDUCE DOOR DRIVE LOADS l COUNTERBALANCE TYPES TORSION SPRING OR GAS SPRING l COUNTERBALANCES ARE NOT REQUIRED FOR LIGHT WEIGHT OR BALANCED PANEL DOORS l RESULTS IN ADDITIONAL WEIGHT & COMPLEXITY

30. SPANNING LARGE OPENINGS l LARGE SPANS CREATE A CHALLENGE l SEVERELY IMPACTS CURTAIN SIZE WEIGHT IN-SERVICE MAINTENANCE l CHALLENGE MAY BE ADDRESSED IN A NUMBER OF WAYS INCREASING PANEL SIZE & SECTION IN A BEAM TYPE DOOR USE OF A HORIZONTAL SLIDING DOOR INNOVATIVE USE OF COMBINATION TYPE DOOR TECHNOLOGY & MATERIALS USE OF INTERMEDIATE GUIDE PILASTER
