Application of FSE approach for structural fire safety assessment of car and motor scooter parks

In the international research field, the application of the FSE approach to study car parks fire behaviour is a well-investigated topic, unlike when the park is intended for motorcycles. Thus, the aim of this work is to investigate several fire scenarios correlated to the two different intended uses. Different fire curves were obtained thanks to thermo-fluid-dynamic zone models knowing Heat Release Rate (HRR) curves from the literature. Results showed that a motorcycle fire can become significant for exodus reason, while the car fire must be considered for structural fire resistance purpose. Several advanced thermo-mechanical analyses were carried out on substructures selected according to FSE criteria, both using natural and nominal fire curves. The results have underlined the importance of the FSE to reduce the structural fire demand.
