Computer-aided evacuation simulation in the field of fire protection

The computer-aided evacuation simulation, like thermal analysis, is part of modern engineering methods. Evacuation simulations not only allow for tailoring escape routes to a specific usage concept, but also make it possible to develop escape routes that deviate from the prescriptive requirements of building regulations. This is particularly interesting in existing buildings with different escape route widths, as permits are often only achievable with considerable effort. The computer-aided evacuation simulation enables the optimal development of escape route concepts. Evidence of compliance with safety objectives can be convincingly provided and demonstrated. This form of pedestrian flow analysis has great potential – it is essential to utilize it to economically implement the safety goals for personal security.

Sinfiro uses specially developed computer programs for this application case, where each person is modeled individually and the floor plan in detail. These computer programs simulate the process of building evacuation, allowing the analysis and optimization of the utilization of individual escape routes. The movement of persons and their interaction with the structural environment are modeled based on empirical studies, observations, and the analysis of damage cases using simplified algorithms with the help of a computational pedestrian flow model.

Evacuation analyses (simulation of evacuation) are successfully used:

– To determine the total evacuation time or the evacuation time of sub-areas (How long does it take until all persons are safe? / How many persons are in safety at which time?) for building facilities, statistically recording and evaluating them considering safety-related aspects.
– To determine the required escape route and exit widths or to optimize escape route guidance in buildings.
– To develop evacuation concepts (organizational fire protection).
– To provide proof that the planned or existing escape and rescue routes are sufficient for the assumed number of persons to meet the building regulations' safety objectives.
