- Abstract
- This document discusses the probabilistic and physical modelling aspects of the initiation and further development of fires in building structures. The occurrence of the initiating events is modelled as a Poisson Process. The further development depends mainly on the amount of combustible materials, the geometry of the fire compartment, the ventilation conditions and the effectivity of fire protecting systems. To describe the resulting temperature time relationship in the structure, both a scientific and a more operational engineering model are presented. Influences with a large degree of uncertainty are treated as random. To make the formulas operational for practical design, numerical values and probabilistic distribution functions based on statistical data are required. As usual for this type of loading, however, statistical information is scarce. Assessment of numerical values and distribution functions will depend to a large extend on subjective estimates. Some indications nevertheless are given.
