DESIGN CRITERIA & KEY ASSUMPTIONS
EXISTING TRUSSES ARE ASSUMED TO BE AS PER TYPICAL LAYOUT SHOWN. OTHER SIZE TRUSSES ARE OUTSIDE OF THE SCOPE OF THIS GENERIC DESIGN.
D1
SPAN = 10.0m OR LESS. ANY SPANS OVER 10m ARE OUTSIDE GENERIC DESIGN BOUNDARIES AND A QUALIFIED ENGINEER SHOULD BE CONSULTED.
D2
PITCHES OF ROOF TO BE 15°, 22.5° AND 25°. ALTERNATE PITCHES BETWEEN 15° AND 25° ARE ADEQUATE. ANY PITCHES LESS THAN 15° OR GREATER THAN 25° ARE OUTSIDE GENERIC DESIGN BOUNDARIES AND A QUALIFIED ENGINEER SHOULD BE CONSULTED.
D3
IT IS RECOMMENDED THAT SEELEY INTERNATIONAL AIR CONDITIONING UNIT IS INSTALLED CLOSEST TO TRUSS TOP CHORD SUPPORTS AS POSSIBLE. I.E. ABOVE TRUSS DIAGONAL WEB.
D4
GENERIC SUPPORT FRAMES ARE DESIGNED FOR WIND CATEGORIES N1, N2 AND N3. REFER TO DETAILS FOR THE DIFFERENT WIND CATEGORIES. ANY WIND CATEGORIES OTHER THAN THE ABOVE ARE OUTSIDE GENERIC DESIGN BOUNDARIES AND A QUALIFIED ENGINEER SHOULD BE CONSULTED.
D5
EXISTING TRUSSES ARE ASSUMED TO BE IN GOOD CONDITION WITH NO SIGN OF DETERIORATION. PREFABRICATED TRUSSES EARLIER THAN 1997 WILL REQUIRE CONFIRMATION OF SUITABILITY IN ACCORDANCE WITH REGULATION 74 OF THE DEVELOPMENT REGULATION 2008.
D6
ADDITIONAL DEFLECTION OF TRUSSES SHOULD BE EXPECTED, HOWEVER THIS MAY BE MINIMAL AND ACCEPTABLE.
D7
TRUSS SPACING @ 600 CTRS IS ASSUMED TO SUPPORT A TILE ROOF. TRUSS SPACING @ 1200 CTRS IS ASSUMED TO SUPPORT A SHEET ROOF
D8
CUTTING OF ANY TRUSS MEMBERS IS NOT ALLOWED
D9
IF ANY DOUBT IN THE INSTALLATION OF DESIGN, PLEASE LIAISE WITH ENGINEER
