Certification
Spantec Systems Pty. Ltd. PO Box 81 MITTAGONG, NSW, 2575 Structural Assessment of Spantec Systems COLORBEAM® Flat Roof Span Tables FRT-‐1.2 October 2015 Publication for NSW, VIC, SA and QLD. This assessment has been certified by Spantec’s third party engineers for the structural design spreadsheets and span tables as described in Spantec Systems publication FRT-‐1.2 October 2015, and consider that they comply with the following Structural Provisions of the Building Code of Australia, 2014: • Volume One, Part B1.4 (c) (ii) • Volume Two, Part 3.4.2.0 (b) The assessment considered the following: • The design spreadsheets to determine the values of awning frame spacing, roof member span, and connection
capacity to populate the span tables in the publication FRT-‐1.2, comply with generally accepted engineering principles and the following Australian Standards: o AS/NZS 1170.0:20002 Structural design actions – Part 0: General principles o AS/NZS 1170.1:2002 Structural design actions – Part 1: Permanent imposed and other actions o AS/NZS 1170.2:2011 Structural design actions – Part 2: Wind actions o AS 4055–2012 Wind loads for housing o AS/NZS 4600:2005 Cold-‐formed steel structures o AS 3566.1–2002 Self-‐drilling screws for the building and construction industries – Part 1: General requirements
and mechanical properties o NASH Standard: 2005 Residential and low-‐rise steel framing – Part 1: Design criteria
• The design capacities of: shear (φvVv), compression (φcNc), tension (φtNt), and bearing (φwRb); and connection capacities have been determined in accordance with Australian Standards AS/NZS 4600:2005 – Cold-‐formed steel structures and AS 3566.1:2002 – Self-‐drilling screws for the building and construction industries – Part 1: General requirements and mechanical properties.
• The design bending capacities about the major axis (φbMbx) of the Colorbeam sections were based on prototype testing, and the design capacity values certified by the consulting engineering practice, Cardno (NSW) Pty Limited – Cardno certification ‘Colorbeam Major Axis Ultimate Flexural Capacities Ref. No. 605504-‐LO-‐43’ dated 7th of February 2008.
• For wind loading in accordance with AS/NZS 1170.2:2002, the following assumptions were considered adequate for the pitched roof applications outlined in publication FRT-‐1.2: o Importance Level of 2 o Design Life of 25 years o Reference Probability of Exceedance (Non-‐Cyclonic Areas) of 1:500 (ultimate) and 1:2 (serviceability) o Serviceability wind speeds have a default minimum value as presented in AS 4055–2012 Wind loads for housing
• The scope of this structural assessment considers design wind pressures for Non-‐Cyclonic Areas only. This certification may be considered as “Evidence of Suitability” under the Building Code of Australia 2014, Volume One Clause A2.2 (a) (iii) / Volume Two Clause 1.2.2 (a) (iii). Information in the Spantec Systems publication FRT-‐1.2 not specifically referenced in this certification is outside the scope of this assessment. This certification does not relieve other parties of their responsibilities. John Trenerry, BE MEM MIEAust (471275) Enertren Pty. Ltd.
