News & Infos Fire disasters
During a fire in a tunnel temperatures can easily exceed 1000°C. These extreme conditions are to be considered in the tunnel lining design process.
News & Infos Transient thermo-mechanical analyses
Any realistic modelling of the structural behaviour should incorporate the analysis of time-dependent heat transfer across the lining.

Fire Safety
The enormous increase of traffic and fire catastrophe  in tunnels underline the necessity of a comprehensive fire safety design of traffic tunnels.
Amongst a variety of topics, such as accident avoidance, efficient passenger evacuation and smoke spread, structural safety is a major concern. In shallow tunnels or cut-and-cover tunnels, for instance, load-bearing capacity of all structural members must be guaranteed at all times in order to eliminate any hazard to human life and buildings on the surface above the seat of fire.
