About this programme

The majority of multi-storey residential buildings in New Zealand have timber or concrete structural frames. Light steel framing is a potential alternative construction form. This project developed the critical test data to inform the development of a design guide for buildings using the high-strength, light-gauge steel found in New Zealand. The research and design guide extended the scope of the National Association of Steel Housing (NASH) Standard Part 1 (New Zealand Building Code) and forthcoming NASH Standard Part 2.
