[en] A 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.
