SAFIR is a computer program that models the behavior of building structures subjected to fire. The structure can be made of a 3D skeleton of linear elements such as beams and columns, in conjunction with planar elements such as slabs and walls. Volumetric elements can be used for analysis of details in the structure such as connections. Different materials such as steel, concrete, timber, aluminum, gypsum or thermally insulating products can be used separately or in combination in the model.
The gas temperatures produced by fire must be entered as input data in the program (some time-temperature curves recommended in international standards are proposed).
From these gas temperatures, SAFIR will first calculate the evolution of the temperatures in the structure. The structure can be made of different materials such as steel, concrete, timber, aluminum, gypsum or thermally insulating products, used separately or in combinations. These temperatures are stored in different files.
The mechanical behavior of the structure is then calculated on the basis of its geometry, its support conditions, the loads that it must withstand and the strength of the materials, taking into account the progressive increase of temperature. The elevation of temperature in the materials produces thermal elongations together with a reduction of strength and stiffness. As a consequence, the displacements of the structure increase continuously during the course of the fire until collapse.
Some 120 academic licenses of SAFIR have been sold to research centers and universities in 37 countries throughout the world, including 12 in the USA, whereas 70 companies use it for designing real projects. Nearly 500 complementary copies of a limited version have been distributed, either for evaluation or for use in masters or PhD programs.
