This article will present a state-of-the-art method which is an amalgamation of several recent research studies from various authors to determine the required structural fire resistance period of buildings. The bespoke approach is based on the Monte-Carlo probability method, which considers not only a range of fully developed compartment fires, but also the phenomenon of travelling fires in increasingly open-plan spaces. An improvement is made on the random selection of compartments depending on the use and area of the individual compartments. A case study is presented in which the probability method is applied to a steel-framed office building in Scotland. The fire resistance period for the building is reduced from the code-required 120 minutes to 60 minutes.

Editorial: Designing for fire resistance - a task for us all

The Grenfell Tower tragedy in London last June was a stark reminder of how rapidly a fire can spread and the horror which it can cause. In the wake of this disaster, the UK construction industry is actively examining what can be done to minimise the risk of similar tragedies in the future. It is likely that one of the recommendations will be a clearer identification of responsibilities, but whatever the outcome it will clearly be helpful for all members of the design team to have a good understanding of all aspects of fire safety, as well as detailed knowledge about those aspects under their direct control.

<h4>A structural fire strategy for an exposed weathering steel-framed building</h4>

A structural fire strategy for an exposed weathering steel-framed building

Performance-based structural fire design can play an important part in delivering iconic buildings. Early design team engagement with critical issues, including fire safety considerations, allows a holistic solution to be developed, in contrast to post-applied fire engineering which could severely compromise the original design intent. Four Pancras Square (London) is a successful example of where early fire engineering engagement has helped deliver an iconic design. The building features an external, fully load-bearing, weathering steel frame, with a storey-deep Vierendeel transfer truss. To allow the weathering steel to develop its protective patina and achieve the desired aesthetic, it must be left untreated and exposed; this is in conflict with traditional fire resistance solutions. This paper documents the key steps undertaken in realising the building and describes how they were tackled at the interface of the fire and structural engineering disciplines. These include quantification of the design goals, selection of the fire constraints, understanding the behaviour of unconventional steel, quantifying thermal exposure for external elements and, finally, quantification of structural response in fire.
