Final report on Contract No 7215-PP/025, 1 July 1998 to 30 June 2001.

It has been demonstrated in previous research that, in the case of fire in car parks or in high buildings, it is generally not necessary to insulate the steel section (beam and/or columns) to obtain a satisfactory safety level. In order to convince national authorities that these kinds of buildings don't need a large duration of fire resistance requirements, real fires were carried out in real unprotected steel buildings in three different configurations:
- A large (high) compartment with a local fire.
- An open car park with a fire scenario involving several cars.
- A closed car park with a fire scenario involving several cars.

The large-scale tests showed that a strong localised fire in a large compartment is not able to lead to the collapse of the building. The tests in an open car park, involving three cars, confirmed the conclusion that an unprotected steel structure can be designed to survive such fires. The tests in a closed car park, involving four cars, likewise concluded that a steel structure can be designed so that the temperatures produced are not able to duct to structural collapse. The tests also confirmed the effect of smoke production within a closed car park and the difficulties of designing an efficient smoke and heat exhaust ventilation system.
