Application of Structural Fire Engineering to an Italian Tall Office Building

Fire Safety Engineering (FSE) is a multi-discipli ne aimed to define the fir e safety strategy for buildings in fire situation, in which structural stability and control of fire spread are achi eved by providing active and/or passive fire protection system. In the following the main aspects of FSE for the structural safety checks in case of fire (Structural Fire Engineering) are shown with reference to Italian and European standards. FSE requires the choice of performance levels, the definition of design fire scenarios, the choice of fire models and generally advanced thermo-mechanical analyses. In the following the application of Structural Fire Engineering (namely the structural behaviour in fire situation) to an existing tall building will be described. This activity is still in progress; nevertheless, the paper provides enough information concerning the structural characteristics of the buildings, the choice of safety performance levels, the active and passive protection systems of the buildings , the identification of fire scenarios through Risk- Ranking approach and, finally, preliminary thermal and structural analyses.
