A DESCRIPTION OF THE PROBABILISTIC AND DETERMINISTIC MODELLING USED IN FIRECAM

To support the introduction of performance-based building regulations in Canada in the year 2003, the National Research Council of Canada (NRC) is developing a computer fire risk-cost assessment model that can be used to assess both the expected risk to life to the occupants and the expected costs of fire protection and fire losses in a building. The computer model that is being developed at NRC is called FiRECAM (Fire Risk Evaluation and Cost Assessment Model). This paper gives a brief description of the probabilistic and deterministic modelling concepts that are used in FiRECAM. In addition, the paper shows the results of its recent application to a six-storey Canadian federal government office building where the existing fire protection systems were being re-evaluated to see how they could be upgraded in a cost-effective manner to meet the current building code requirements.
