Variation in risk category in methods of calculation of the modified fire load density

Abstract

The management of fire safety in buildings is conducted in accordance with the type of use-risk category (Building occupancy code). For Building type XI "libraries and archives" and XII "industrial, workshops and warehouses", the determination of the risk category involves the calculation of the modified fire load density, which can be done by two methods used interchangeably by the technician: deterministic and probabilistic. This study aims to investigate variation results obtained with the calculation of the modified fire load density using two methods and the classification of the Building occupancy code. The performed calculations referred to real buildings of type XII, with defined and distinct materials and activities. The different results determine a variation in the risk category, which consequently, will define the technical criteria to be applied to the Building occupancy code in the implementation for Building Fire Safety measures.
