EVACUATION COMPUTER MODELLING AND SIMULATION IN COMPLEX BUILDINGS.

To assess the adequacy of the safety aspects of people in the buildings, it is necessary to make an accurate estimate of time required for occupants to move a safe place. There are various ways of approaching the problem of evacuating a building. The analytical calculations, based on the standards regulations and requirements, pose a quick solution to the problem by calculating occupancy capacity, travel distance and dimensions of the means of egress. But when it comes to a complex building, these approaches may be insufficient. This paper examines the evacuation process of places and spaces of a passenger rail station consisting of different uses (assembly, entertainment, transport services, etc.) through Evacuation Modelling and Simulation. The results allowed to determine the impact of different geometry conditions of the building and physical and behavioral occupants characteristics in the calculation of the evacuation process and its impact on the required egress safe time in an emergency situation.
