Abstract

Shopping centers and event halls established today are to be brought only with difficulty in harmony with the demands of the building code regulations and directives concerning the escape routes. Engineering methods like simulation-models for evacuation dynamics for the calculation of the evacuation time supply an indispensable instrument to find a compromise between a safe enough and coevally economical building. With simulation models it can be proved computational for example that in case of fire persons can leave a building quickly enough and without dubious congestions so that they are not endangered by smoke and fire gases. The difficult is that it is impossible to estimate the achieved safety level of a simulation because of the absence of a probabilistic safety concept. The question is: “How safe is safe enough”? In this article a global probabilistic safety concept is presented which in case of evacuation (for example in case of fire) starts from an extraordinary unfrequent event. The essential safety depends on the authoritative side conditions, varying by usefulness of a building, for the endangering of persons.
