Fire resistance reliability


This research is intended to provide a risk-informed basis for structural fire resistance requirements. Work to date has been done for single-level industrial and densified residential occupancies.

As part of this research, a comparison of primary structure fire resistance requirements between similar international jurisdictions was completed. The table pictured below demonstrates the required structural fire resistance in minutes as a function of height up to 20 storeys for residential buildings in New Zealand, the USA, Australia, Canada and England. Information is indicative only as requirements may also depend on other factors, such as the number of escape routes.
