- Modified fire load determination in buildings Methods, results and selection criteriaPublication . Cadete Pires, Cristina Maria Paulo; Veiga, RuiThe determination of the risk classification categories, applicable to the uses type-XI «libraries and archives» and XII «industrial, manufactories and warehouses» involves the modified fire load calculation, which can be implemented through two methods to be used indistinctly by the technician: deterministic and probabilistic. This study conducted in the fire safety area, aims to investigate the calculation results of the modified fire load by the two methods and the classification of the UT. The calculations were made based on a real UT with defined activities and materials. Obtaining different values in UT XII, determine contradictory categories of risk, which will detract from the technical conditions required by the regulation to UT. The results led us to conclude that the legislator who hasn’t define which method to use and thereby leaves to the discretion of each technician the selection and consequently the risk category determination of the UT, cannot achieve the goal it has set in RJ-SCIE: the standardization of the demanded level in implementation of measures SCIE.
- Variation in risk category in methods of calculation of the modified fire load densityPublication . Cadete Pires, Cristina Maria Paulo; Veiga, Rui; Miguel, IsabelThe 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.
