In this paper the quantitative risk analysis procedure has been used to face two specific aspects of the fire safety design in road and rail tunnel: • the smoke control system effectiveness; • the spalling effect and structural reliability of the liners. The first example deals with the risk comparative assessment of two alternative systems for smoke control in a road tunnel. The societal risk indicator has been used to select the more effective system. The second one aims to consider a reliability based approach for structural design of the tunnel liners in order to identify the design fire load preventing from the spalling effect at a given probability level. © 2009 WIT Press.

Abstract
In this paper the quantitative risk analysis procedure has been used to face two specific aspects of the fire safety design in road and rail tunnel: • the smoke control system effectiveness; • the spalling effect and structural reliability of the liners. The first example deals with the risk comparative assessment of two alternative systems for smoke control in a road tunnel. The societal risk indicator has been used to select the more effective system. The second one aims to consider a reliability based approach for structural design of the tunnel liners in order to identify the design fire load preventing from the spalling effect at a given probability level. © 2009 WIT Press.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
