Three methods for the calculation of equivalent fire duration were analyzed. These are the methods of the standards EN 1991-1-2, GOST R 12.3.047-2012 and the methods based on fire modeling by FDS 6. Various rooms and their structures (concrete, non-protected and fire-proofed steel), and fire sources were considered. It was found that the GOST R 12.3.047-2012 method gives higher values of equivalent fire duration in comparison with the EN 1991-1-2 and FDS 6 methods. Not only the equivalent fire duration, but also actual fire resistance limits were evaluated by FDS 6 taking into account the heating of structures. It was shown that FDS 6 can be successfully used in cases when the standards are not applicable or give overestimated results.
