1. Introduction
In general, since the turn of the 19th century there has been steady improvement in the means by which adequately safe structural response in fire is designed for and implemented. The aspirations for acceptable building performance have become better defined and documented in regulatory literature and design codes. Understanding of fire dynamics and thehermo-mechanical behaviour of construction elements and buildings as a whole has advanced greatly. Fire protection products (intumescent paint to steel for example) have evolved to be highly effective systems for which thickness can be speci- fied to the micron to meet given performance criteria. However, the fire resistance ratings against which satisfactory behaviour of structural elements is benchmarked (determined by the duration of standardised furnace-test heating regimes experienced by an element before defined performance criteria are breached) are specified in 15-min intervals (for example 60, 75, 90 min) that relate to figures in prescriptive guidance which have remained largely unchanged since the post-war era [1]. This despite the fact that fire resistance test standards [2] state that any furnace test duration may be applied. Does the 15-min grading system therefore represent a crudeness that limits the reliability and consistency of the overall design process? This paper presents the authors’ views on this issue, and is posed as an opinion piece intending to stimulate discussion amongst the fire safety community.
