This paper presents a numerical model for beam-slab floor systems in which a single compartment is subjected to fire. The system consists of a composite steel-concrete slab and a bare steel beam. Several idealisations are made in order to illustrate important behavioural patterns which occur under fire conditions. Nonlinear analyses are undertaken using an advanced yet computationally efficient computer program which accounts for the large displacement behaviour at elevated temperatures. The model is shown to capture the main parameters influencing the performance of the system under fire. In particular, the significance of axial restraint and thermal expansion on the overall deformation and capacity of the system is demonstrated. It is indicated that thermal expansion may have beneficial as well as detrimental consequences on the performance, depending on the particular structural configuration under consideration. The paper also closely examines the level of dependency of the response on the sequence of application of loading and elevated temperature as well as the assessment of the overall system response from consideration of the respective responses of individual components. It is shown that such concepts may be effectively employed in undertaking detailed studies for improved quantification of the fire resistance of beam-slab systems with a view to the development of more rational performance-based design procedures.

This paper describes numerical models constructed to simulate the response of composite steel/concrete building floors under fire conditions. In particular, this study deals with two of the fire tests recently undertaken on a full-scale multi-storey building at Cardington, UK. The analysis is carried out using a structural analysis program which accounts for both geometric and material nonlinearities, and which includes temperature-dependent constitutive models for steel and concrete materials. The approaches used to represent the various structural details are discussed, and the procedure employed for incorporating the experimentally measured temperature profiles and histories is outlined. For the two tests considered in this investigation, the numerical results are in general agreement with the experimental data, particularly in terms of the magnitude of vertical deformations induced in the floors at elevated temperatures. Close examination of the numerical and experimental findings provides an insight into the complex interactions that occur in the structure at elevated temperatures. Most significantly, the influence of the restraint to thermal expansion of the heated floor area, which is provided by the surrounding parts of the structure, is shown to be of paramount importance. The increasing confidence that can be placed in numerical models as well as the improved understanding of the structural fire response may be used in developing more realistic and cost-effective design methods which are based on the actual structural response rather than that of isolated members.
