Fire Safety Engineering

The Fire Testing Centre, a laboratory approved for fire resistance by the French Ministry of the Interior, carries out your fire safety engineering studies under conventional fires and real fire scenarios, , for all construction methods (reinforced and prestressed concrete structures, steel and composite steel and concrete structures, wood structures).

The approach of a fire safety engineering study.

Fire safety engineering consists of assessing the behaviour of a structure or a building under fire, considering all its specificities (its function – storage, residential, etc., and its types of structure – concrete, steel, wood, etc.).

The first step is to define the safety objectives and associated performance criteria. These may be:

Fire resistance time of the structures
Fire stability of the structures compatible with the evacuation of people and the intervention of emergency services
Non-collapse in chain of structures
Non-collapse towards the outside.

The fire safety engineering study then proceeds in several steps:
Step 1: Preliminary risk analysis
Step 2: Design fire scenario studies
Step 3: Fire development simulation, thermal action assessment
Step 4: Assessment of the thermomechanical behaviour of structures

Our skills

and our tools.

Fire safety engineering mobilises many skills covered by our teams of expert engineers:

Combustion, fluid mechanics, thermics..: fire development, and smoke movement.

Structural mechanics: thermo-mechanical response of concrete, reinforced concrete, pre-stressed concrete, steel, composite and wood structures and of compartmentalisation elements.

Different means can be used in a fire safety engineering study:

Calculation methods
– Simplified methods (analytical, defined in Eurocodes and rules of the art)
– Advanced methods (numerical simulations using FDS for fire development and SAFIR for structural behaviour calculation)

Experimentation

– Input data for calculation methods to extrapolate results from small-scale tests
– Conducting full-scale tests if calculation methods do not exist

Statistical data

– Input data for calculation methods
– For probabilistic analyses and expert judgements

Sectors of activity.

The studies carried out by our teams of expert engineers cover the following sectors of activity:
Buildings (residential, offices, ERP – building open to public)
High-rise buildings (IGH in French)
Classified installations (ICPE in French)
Engineering structures (bridges, footbridges)
Underground works (tunnels, cut and cover tunnels)
Nuclear facilities (INB in French)
