Abstract
Using the characteristics of a fire scenario as a starting point, the authors illuminated the risks using textile membranes as a building material. The burning away of the membrane and the opening of a natural smoke evacuation was chosen for further studies. Using input from validation experiments the authors simulated these experiments in FDS to explore the agreement. There was uncertainties in finding the correct input data, especially determining the heat of combustion and the width of the pyrolysis range. Results showed that it is possible to use the burn away option in FDS to model the opening up of a hole in textile membranes. However, using textile membrane as a fire safety precaution for natural smoke evacuation is not reasonable.... (More)

However, using textile membrane as a fire safety precaution for natural smoke evacuation is not reasonable. Furthermore the report shows that it is possible to import complex geometries to FDS and use the burn away option as well. However, at the moment it is impossible to accurately simulate complex geometries for fire safety design purposes. (Less)
