This paper proposes a modelling strategy to simulate a hospital evacuation. The capabilities of two commercial evacuation models, STEPS and Pathfinder, are explored to evaluate their ability to simulate this type of scenarios. This includes the study of the issues concerning the simulation of horizontal hospital evacuation (i.e. calibration issues, capabilities and limitations). A case study is presented in this paper by using STEPS model. Read More...

In an MSc thesis conducted at Lund University, Sweden, a validation study of FDS version 6.2.0 on the area of external fire spread was conducted. The validation study was performed using experimental data from a large-scale fire test on an SP FIRE 105 test rig in Borås, Sweden. The SP FIRE 105 test rig is a test method for facade systems simulating the impact on the overhead facade of a fire on the ground floor of a three-story apartment building. For this particular test, non-combustible calcium silica boards were attached to the facade and temperature measurements took place at six different heights. Read More...
