| Abstract: |
This paper deals with possibilities to update existing road tunnels in order to fulfill up to date requirements regarding structural fire protection. Besides the upgrading of tunnels with structural fire protection systems (like e.g. fire protection sheets) there is also the possibility of numerical investigations. In research projects carried out on behalf of the Federal Highway Research Institute (BASt) numerical investigations for the proof of sufficient structural fire protection have been done for common road tunnel types. Additionally the influence of different fire loads and fire durations on the bearing capacity of the structures have been investigated. The results of these research projects have been used to define a procedure how to investigate existing tunnels regarding structural fire protection. The research results have also been the basis for a current update of national standards for tunnel construction. |
