The principles governing the behaviour of composite, framed steel structures in fire conditions were discussed. These principles were based on the analysis of the response of single structural elements under a combination of end restraints and thermal actions representing the surrounding structure. It was deduced that composite steel structures possesed larger strength through adopting large displacement configurations.
