As part of a DETR funded PiT (Partners in Technology) project the BRE Centre for Fire Safety Engineering (previously the Structures in Fire Group) conducted extensive computational and analytical studies of the behaviour of steel-framed composite structures in fire conditions. This work was undertaken in collaboration with Corus PLC and Imperial College London. The results were presented in the form of a main report, which identified the main findings, together with numerous supplementary reports which explored various phenomena in detail. The reports produced at Edinburgh are available for download as indicated below.
