Abstract
This study deals with the assessment, using probabilistic methods, of people’s fire safety in
buildings. The problem is addressed by modelling the evacuation of people from the fire- and
smoke-threatened area. The buildings considered are assumed to be designed according to the
Icelandic fire prevention regulation. The following types of buildings have been chosen for
analysis: a dance hall, a sports hall, an office, a school, a hotel and an home for the elderly.
For each case, a limit state function simulating the life safety is constructed. These functions
are expressed in terms of analytical smoke development models and evacuation models. The
analytical smoke development model is derived using the computer model, HAZARD. The

This study deals with the assessment, using probabilistic methods, of people’s fire safety in
buildings. The problem is addressed by modelling the evacuation of people from the fire- and
smoke-threatened area. The buildings considered are assumed to be designed according to the
Icelandic fire prevention regulation. The following types of buildings have been chosen for
analysis: a dance hall, a sports hall, an office, a school, a hotel and an home for the elderly.
For each case, a limit state function simulating the life safety is constructed. These functions
are expressed in terms of analytical smoke development models and evacuation models. The
analytical smoke development model is derived using the computer model, HAZARD. The
analytical evacuation models account for detection time, response and behaviour time as well
as the time needed for movements to a safe area. Each parameter in the limit state functions is
described by an appropriate probability distribution. The probability of accidents is assessed
using the safety index method, FORM. The b-indices are calculated, using the computer program
package, STRUREL, for each limit state function and the sensitivity of various parameters
is checked in order to detect the most important parameters. (Less)
