In the frame of the European RFCS TRAFIR project, three large compartment fire tests involving steel structure were conducted by Ulster University, aiming at understanding in which conditions a travelling fire develops, as well as how it behaves and impacts the surrounding structure.


During the experimental programme, the path and geometry of the travelling fire was studied and temperatures, heat fluxes and spread rates were measured. Influence of the travelling fire on the structural elements was also monitored during the travelling fire tests.


This paper provides details related to the influence of travelling fires on a central structural steel column.


The experimental data are presented in terms of the gas temperatures recorded in the test compartment near the column, as well as the temperatures recorded in the steel column at different levels. Because of the large data, only fire test one results are discussed in this paper.



This work was carried out in the frame of the TRAFIR project with funding from the Research Fund for Coal and Steel (grant No 754198). Partners are ArcelorMittal, Liège University, the University of Edinburgh, RISE Research Institutes of Sweden and the University of Ulster.
