It explains how structural designers should apply existing design criteria and concepts to the design of steel sheds falling within a defined scope. It applies to buildings with structural frames made predominantly from cold-formed steel and clad predominantly with steel wall and roof sheeting. It promotes consistent interpretation of critical requirements for the structural performance of steel sheds. It does not replace the National Construction Code (NCC), its referenced standards and other guidance publications but should be read in conjunction with them.  \nThe Building Code of Australia (BCA) comprises Volumes 1 and 2 of the National Construction Code (NCC) published by the Australian Building Codes Board. The NCC is enabled in each state and territory by relevant local legislation. References to the BCA and NCC in this edition are to NCC 2014.  \nLIMITATIONS  \nThis Guide is not appropriate for the design of:  \n􀁸 Habitable buildings of any kind, and any structures attached to them.  \n􀁸 Silos and similar produce stores where stored contents apply vertical or lateral wall loads.  \n􀁸 Buildings larger or smaller than the dimensions described in the Scope (see Section 1.5) . The design principles and guidance may be applicable to a wider range of buildings, at the designer’s discretion. For habitable buildings, the NASH Standard – Residential and low-rise steel framing, Part 1: Design criteria and related publications should be consulted. For low-rise commercial buildings, refer to either the NASH Standard or other relevant standards and publications.  \nThis Design Guide focuses on structural design requirements. Depending on their use and NCC classification, complete buildings will require additional design considerations as specified in the NCC.  \nABOUT THE STEEL SHED GROUP  \nThe Australian Steel Institute Steel Shed Group is a special interest group formed and funded by industry members. The Steel Shed Group promotes compliance for engineering, documentation, supply and construction standards for the steel shed industry via technical publications, education and awareness programs.  \n1.2 WHAT IS A SHED?  \n’Shed’ is a very common term in the community. Buildings fitting the general description of’shed’ may be used for a wide range of purposes. According to the Macquarie Dictionary, a shed is:  \n1. A slight or rough structure built for shelter, storage, etc.  \n2. A large, strongly built structure, often open at the sides or end.  \nWhilst ‘private garage’ is a defined term in the NCC, shed, carport, workshop and farm building are not. Structural designers cannot rely solely on a proposed building’s description. They must consider whether the building will be accessible to the public, used as a factory or workplace, as an assembly point or even as an emergency refuge.  \nFor the purposes of this Design Guide:  \n􀁸 A shed is any freestanding non-habitable general purpose building used for domestic, commercial, industrial or agricultural purposes. A residential shed is one constructed on a residential allotment and used predominantly for private, domestic purposes.  \ndesign guide  \nportal frame steel sheds and garages, second edition  \n 7  \n􀁸 A garage is a special-purpose freestanding building designed to shelter vehicles and with at least one vehicle-sized door. Garages may be residential or non-residential. All other vehicle shelters, including those attached to buildings, are carports and are not covered by this Guide.  \nBuildings supplied by Australian shed manufacturers are frequently used as NCC Class 10a buildings. However, many may be used or adapted as Class 6, 7, 8 or 9b buildings, provided they are designed or modified accordingly.
