Abstract
Experience shows that the assessment of fire resistance of steel elements based on European standards is conservative, while advanced methods are complex and time consuming. The analysis of existing methods for the tested steel beam exposed to bending and standard ISO fire was conducted in the scope of the international Round Robin study. The comparison of results shows that advanced methods provide non-uniform assessments. Nevertheless, advanced methods are necessary for improving standard methods that overestimate fire resistance of this trivial problem.
Highlights
Fire is an extraordinary action whose destructive effect on structures should be prevented as much as possible, and its effects should be anticipated
Differences in results obtained by advanced methods for calculating fire resistance of steel beams were analysed, and the results were compared with experimental results
A wide spreading of the Round Robin study results is caused by two factors - assumptions made by as well as the general craft of the participant and how the chosen methods are used, and inconsistent failure criteria used by the participants
Summary
Fire is an extraordinary action whose destructive effect on structures should be prevented as much as possible, and its effects should be anticipated. For this purpose, fire resistance should be adequately modelled. Participants in the study included universities, testing laboratories and consultancies, whose representatives may be considered experts in the field of fire engineering Differences in results obtained by advanced methods for calculating fire resistance of steel beams were analysed, and the results were compared with experimental results. The measured data on steel properties and measured temperatures obtained during furnace testing were made available to the participants. A similar Round Robin of laboratory fire tests, which allowed comparison with the Round Robin calculations, was conducted by the EGOLF, which is the European Group of Organisations for Fire Testing, Inspection and Certification [5]
