The comparison of the results of a full scale evacuation test to the calculation method of Hungarian regulations to the Pathfinder softwaren

Csaba Szilagyi


Action of people in different building has large scale of uncertainty and there is poor availability of experimental data describing it. Evacuation software might be a solution of the problem, but their validation is a key issue. To analyze these key questions,  a full scale test was conducted with more than 200 persons participating in it. The test was divided to two phases, first the comparison to Hungarian regulations with a numerical method taking the speed, the width of doors and stairs into consideration and then the comparison to three calculation methods of Pathfinder software. The criteria of calculation defined by the AHJ resulted two different egress scenarios. There were interesting differences between the results of the full scale test, the calculation and the three simulation methods, and also the reasons of the differences were interesting.
