SAFIR is a computer program developed by Jean-Marc Franssen at University of Liege  and Thomas Gernay at Johns Hopkins University 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.

As an example, the picture below shows the deflections, calculated with SAFIR, of a steel structure subjected to fire (courtesy BuroHappold Engineering).

Safir description  

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).
