Fire Safety Risk Analysis of a Community Centre

A systems approach to fire safety is a way to evaluate fire safety of buildings, especially large and complex buildings. One tool for building fire risk analysis is the computer programme FIRE (Fire Simulation Program) de veloped at Worcester Polytechnic Institute (WPI) in USA by Professor R. Fitz gerald and his group. The computational utility of the code was improved and adapted to the Finnish environment by Technical Research Centre of Finland (VTT) and two engineering consultants, Rakennus-Ekono and LCA-Engin eering.

We simulated fires in a four-floor building where one wing (single fire com partment) was selected for simulation. We chose four representative room types in the building for which fire engineering data were selected. By simulation, we studied the impact of different design alternatives to fire risk of the total building. Fire risk in each design alternative was computed as expectation of loss. Costs caused by structural changes and active fire safety systems were taken into account. The compilations proved that it is possible to design differently from the current fire code and still reduce the fire risk level. FIRE does not yet support the evaluation of life safety, but the results can be used for that purpose indirectly.
