NASH Standards

These NASH Publications are referenced in the National Construction code (NCC) and therefore form a deemed-to-satisfy solution.

NASH STANDARD – RESIDENTIAL AND LOW-RISE STEEL FRAMING, PART 1: DESIGN CRITERIA

This Standard covers both residential and commercial low-rise steel framed buildings and is fully limit-state based and will enable structural engineers to create efficient and economical steel framing systems. It sets structural adequacy and serviceablility aspects of the design criteria for everyday steel-framed structures like houses as well as other low-rise residential and commercial buildings.

This Standard is referenced in both Volumes of the National Construction Code as a deemed-to-satisfy solution.

NASH STANDARD – RESIDENTIAL AND LOW-RISE STEEL FRAMING, PART 2: DESIGN SOLUTIONS

This Standard provides design solutions for wind classifications N1 to N4 and C1 to C2. The Standard is set out in the order of the design process ie starting at the roof and continuing through to the foundations. The Standard covers roof beams and rafters, walls, floors, bracing, connections, durability, tolerances etc. The Standard allows for items to be designed in accordance with NASH Standard Part 1. These items can also be used in conjunction with items designed in accordance with Part 2.

This Standard is referenced in both volumes of the National Construction Code as a deemed-to-satisfy solution.

NASH STANDARD – STEEL FRAMED CONSTRUCTION IN BUSHFIRE AREAS

This updated Standard is based on non-combustible construction using steel framing, steel roof cladding and non-combustible wall systems. This provides the basis for economical and robust solutions. It was developed following full scale bushfire simulation complemented by small scale tests and the application of fire engineering principles. It gives two solutions, one covering lower BAL’s (BAL-12.5, BAL-19, BAL-29 and BAL-40) and a separate solution for flame zone (BAL-FZ), based on AS 3959 BAL definitions.  New inclusions in this updated version:

• Storage platforms in ceilings not covered but you can construct a storeroom in the ceiling
• Gives solutions for tiled roof for BAL-12.5 to BAL-40
• Extends roof pitches to cover all roofs for BAL-FZ
• Extends solution to cover cathedral ceilings in BAL-FZ
• Specific solutions for Class 10a buildings (garages/sheds)
• Covers roof skylights/windows
• Clarified requirements for HVAC and service ducting
• Additional drawings/details

This Standard is referenced in Volume Two of the National Construction Code as a deemed-to-satisfy solution.

NASH HANDBOOK – DESIGN OF RESIDENTIAL AND LOW-RISE STEEL FRAMING

This Handbook supports the NASH Standard – Residential and Low-rise Steel Framing, Part 1: Design Criteria. It covers the structural design of floor, wall, roof and bracing systems as well as assisting with the design of connections, testing structures, durability, fabrication and construction practices. Design tables and manufacturers testing data are included for connections.
