The aim of this project is to develop uniform European design rules for protected and unprotected cellular beams (CB) constructed of rolled sections subjected to fire. The use of cellular beams (CB) will be increased by minimising and optimising the cost of fire protection and by allowing a wider use of unprotected CB. This will greatly benefit long span construction. These results will be achieved based on the development of a new design code of single CB subjected to fire as well as an extended methodology considering the whole floor structure and the beneficial effects of the adjacent members. The reliability of the developed tools will be based on large-scale tests in order to provide a cost-effective design methodology. A set of practical design recommendations will be developed in order to satisfy all the requirements of fire-safe engineering.
Final report EUR 25122 EN, 2012
In the scope of this project, it is clearly demonstrated that steel structure, if designed appropriately, fulfils the safety requirements in case of fire which will be given in terms of "non-progressive collapse" and "non dangerous failure type". On the basis of a series of parametric studies, several simple design rules as well as some key construction details are proposed in order to help all engineers to design safe steel structures for single storey industrial buildings.

The aims of the present research are to improve and to extend the existing physical models, in order to calculate temperature development within various types of structural elements, by including transient state effects. The verification of the current Eurocode models has been performed on the basis of experimental and numerical results.
The primary aim of this research was to prove that the fire safety of steel single-storey buildings is sufficient, in the absence of passive fire protection, by means of risk assessment and structural simulations showing that the safety of people and firemen is ensured. The safety of firemen is guaranteed by a safe failure mode and non-progressive collapse behaviour of the structure. This methodology was also extended to low level multi-storey structures (two to four storeys).
A CFD-based engineering methodology has been developed for determining the thermal behaviour of structural elements in steel/composite-framed buildings subjected to natural fires.
