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
