In the context of the CEVA link (Cornavin – Eaux-Vives – Annemasse), a rail tunnel project designed to connect the Cornavin railway station in Geneva, Switzerland with the station in Annemasse, France, Efectis was mandated to perform advanced fire calculations on the main structures.

téléchargement (2)The aim of this study is to verify the fire behaviour of the more significant cross sections of the infrastructure, in accordance with standard calculation methods applied to underground transport systems. As it is a new project, the European TSI regulatory must be applied and the RABT-ZTV time-temperature fire curve (also known as the Eureka curve) is prescribed for fire resistance of the structures. The spalling effect has been defined by the reduction of the initial concrete section.
