Fire Calculations

Beams and Integrated floor beams

  • ArcelorMittal Beams Calculator
    Calculation of steel, partially encased, composite, or integrated beams (SFB, IFB type A and B) in cold and fire conditions. The software complies with Eurocodes 3 and 4 and the current state-of-the-art regarding the calculation of integrated beams.
  Setup ABC version 3.49



  • ArcelorMittal Cellular Beams ACB
    Predesign of Cellular beams with circular openings in cold and fire conditions.
    Predesign of steel and composite cellular beams with sinusoidal openings in normal and fire situation.


  • ArcelorMittal-CTICM Columns Calculator A3C
    Calculation of steel and composite columns (partially or totally encased with concrete) in cold and fire conditions. The software fully complies with EN version of Eurocode.
  Setup A3C version 2.93



Partially protected composite floor

  • MACS+

    This software designs composite floor slabs at elevated temperatures by taking into account the enhancing effects of the membrane action in slab. MACS+  also checks perimeter beams and provides a critical temperature for each of them.

One zone model

  • OZone

    Gas temperature in the event of fire according to EN 1991-1-2 and corresponding steel temperature according to EN 1993-1-2.

Industrial Halls

  • LUCA

    “LUCA” is software accompanying a design guide for industrial halls in fire conditions. This tool calculates displacements and additional horizontal forces that appear in industrial halls during fire enabling the engineers to consider their effect in the design in order to avoid collapse or risk of human life. Software was developed within RFCS project RFS2-CR-2007-00032.
