Abstract
This paper presents a probabilistic simulation approach to assessment of
the fire endurance of a wooden load-bearing beam in a fire. The approach
introduces several novel modelling techniques developed by VTT, such as the
probabilistic fire simulator which is an interface enabling to run fire
simulation models in the Monte Carlo mode and the time-dependent event-tree
method which enables to take into account the active fire safety measures such
as detectors, first-aid fire fighting, sprinklers and fire brigade
intervention. Also the simulation of the response to heat and the mechanical
performance of the structure are carried out using the Monte Carlo technique.
The charring rate of the wooden beam is calculated by a new model that
includes explicitly the principal sources of uncertainties and variabilites.
The results show explicitly the effectiveness of different fire safety
measures in reducing the risk of structural failure.
