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 are calculated. For the mechanical analyses based on 3D beam finite elements, the software can calculate the elastic torsional stiffness of the section.
SAFIR has been developed from the beginning as a tool for modeling the behavior of structures subjected to the fire. The link between the thermal analysis and the structural analysis is thus quite straightforward. It is founded on high performance finite elements, yet it runs on quite ordinary Windows based PC. Its utilization is not complex, provided that the user has a good knowledge of non linear modeling. Training sessions can be organised at a reasonable prize (800 euros per day, excluding VAT).
