“…According to Buchanan et al [13] ''Beam behaviour is very sensitive to the stress condition relative to the temperature-reduced proportional limit and yield stress.'' both the proportional limit and yield stress play an important role in the behaviour of steel beams at elevated temperatures.…”

“…The computer program FEMFAN from the Fire Engineering Research Group at Nanyang Technological University has been used by Tan et al [8][9][10][11], to study the behaviour of a number of steel frames under fire conditions. Franssen et al [12] developed a computer program SAFIR, which was used by many researchers [13][14][15]. Also a number of researchers [16][17][18][19][20][21][22][23][24] used commercial FEA software ABAQUS to carry out the structural analysis of steel frames at elevated temperatures.…”

In this paper a robust static-dynamic procedure has been developed. The development extends the capability of the Vulcan software to model the dynamic and static behaviour of steel buildings during both local and global progressive collapse of the structures under fire conditions. The explicit integration method was adopted in the dynamic procedure. This model can be utilized to allow a structural analysis to continue beyond the temporary instabilities which would cause singularities in the full static analyses. The automatic switch between static and dynamic analysis makes the Vulcan a powerful tool to investigate the mechanism of the progressive collapse of the structures generated by the local failure of components. The procedure was validated against several practical cases. Some preliminary studies of the collapse mechanism of steel frame due to columns' failure under fire conditions are also presented. It is concluded that for un-braced frame the lower loading ratio and bigger beam section can give higher failure temperature in which the global structural collapse happens. However, the localised collapse of the frame with the higher loading ratio and smaller beam section can more easily be generated.The bracing system is helpful to prevent the frame from progressive collapse. The higher lateral stiffness of the frame can generate the smaller vertical deformation of the failed column at the restable position. However, the global failure temperature of the frame is not sensitive to the lateral stiffness of the frame.

“…For example, Wang and Moore (in Becker, 2002) developed a three-dimensional model of a steel frame building with semi-rigid connections to view the structural behaviour at elevated temperatures. Similarly, the finite element software Vulcan was used at Sheffield University for the analysis of a three-dimensional model of a concrete-and steel-framed building subjected to high temperature (Buchanan et al, 2004;Chen and Liew, 2005;Chen and Young, 2007). The computer programme finite element model FAN is used by the Engineering Research Group of the Nanyang Technological University (Huang et al, 2009) to understand the behaviour of framed structures under high-temperature conditions.…”

Purpose Progressive collapse because of high temperatures arising from an explosion, vehicle impact or fire is an important issue for structural failure in high-rise buildings. Design/methodology/approach The present study, using ABAQUS software for the analysis, investigated the progressive collapse of a two-dimensional, three-bay, four-storey steel frame structure from high-temperature stresses. Findings After structure reaches the temperature results like displacement, stress axial load and shear force are discussed. Research limitations/implications Different temperatures were applied to the columns at different heights of a structure framed with various materials. Progressive collapse load combinations were also applied as per general service administration guidelines. Originality/value This study covered both steady-state and transient-state conditions of a multistorey-frame building subjected to a rise in temperature in the corner columns and intermediate columns. The columns in the framed structure were subjected to high temperatures at different heights, and the resulting displacements, stresses and axial loads were obtained, analysed and discussed.
