SAFIR - modelling software for constructions under fire

SAFIR is a computer software for the simulation of the behaviour of building structures subjected to fire. The fire is introduced as a data (in term of a curve giving either the evolution of the gas temperature in the fire compartment or the evolution of the net flux on the surface of the structure) and the software calculates the evolution of the temperature in the structural elements witch can be discretized in 2D or 3D. The structure is then discretized by means of truss, beam or shell finite elements and the evolution of the structure's displacements, stresses and strains. For the mechanical analyses based on 3D beam finite elements, the software can calculate the elastic torsional stiffness of the section.
