[en] Numerical modelling is a very useful tool to predict the fire resistance of a structure, or to reproduce artificially what has happened during a real fire. SAFIR, a non linear computer code
developed at the university of Liege-Belgium, is specifically written for modeling the behavior of
structures subjected to fire. It allows a determination of the temperatures in the structure esulting
from the fire and, in a subsequent analysis, determination of the successive positions of equilibrium of the structure until collapse. SAFIR program accommodates various elements for
different idealizations, different calculation procedures and several material models incorporating
stress-strain behaviour. The elements include 2-D SOLID, 3-D SOLID, BEAM, SHELL and TRUSS elements. The stress-strain material laws are generally linear-elliptic for steel and nonlinear for concrete. This paper introduces the main hypotheses, the possibilities and the validity of this program. Comparisons of test results and simulated results by SAFIR program for concrete
structures, steel structures and concrete-steel composite structures are presented.
