Buckling curves of hot rolled H steel sections submitted to fire
Report of the research work at the base of the design equation introduced in Eurocode 3 (EN 1993-1-2) for the stability of steel columns under axial loading or combined axial and bending loading
Numerical simulations of fire resistance tests on steel and composite structural elements or frames
peer reviewedA computer program for the analysis of steel and composite structures
under fire conditions is presented. It is based on the finite element method
using beam elements with subdivision of the cross section in a rectangular
mesh. The structure submitted to increasing loads or temperatures is
analyzed step-by-step using the Newton-Raphson procedure. The thermal
problem is solved by a finite difference method based on the heat balance
between adj acent elements. Comparisons are made between full scale tests on
steel and composite structural elements and frames and the results given by the
numerical simulations. The agreement appears to be quite good. Furthermore are
discussed the new possibilities given by this numerical computer code.REFAO-CAFI

Computer aided fire resistance for steel and composite structures
peer reviewedThis paper introduces the main features of the computer software CEFICOSS. 2D fnite differences are used for the transient non linear thermal analysis. 2D Bernoulli beam finite elements are used for the transient large displacement mechanical analysi
Computer assisted analysis of the fire resistance of steel and composite steel-concrete structures
This reasearch report describes the computer software CEFICOSS, including experimental tests performed on composite elements to validate the software. CEFICOSS can be seen as the predecessor of SAFIR
Effects caused on the structure by localised fires in large compartments
A description is given of the small-scale steadstate tests made by Hasemi in Japan with the aim of measuring the heat flux transmitted by a localised fire to the ceiling or to a beam located above the fire. The parameters that influence the heat flux have been mentionned and an empirical model has been proposed, allowing the prediction of the heat flux.It is shown here how the model has been applied to full-scale transient fires. The model allows the calculation of the transient temperature in steel beams with a reasonable accuracy
A Simple Model for the Fire Resistance of Axially-Loaded Members According to Eurocode 3
New buckling curves have been developed for axialy loaded steel members subjected to fire. The model is based on extensive numerical simulations calibrated on several dozens of full scale experimental test results. This model has been subsequently included in Eurocode 3
