Considering the many possibilities of industrial buildings are being under fire, human losses or casualties are a big challenge to be spared in addition to asset and properties losses as well. The improvement of fire simulations via FDS (Fire Dynamic Simulators) programs is very helpful to investigate the transient fire and its spread inside the building under fire to be used for the methods of fire spread reduction within the industrial building inner space in case of partially space is under fire. This paper illustrates the effect of ceiling shape of the industrial building in the spread and thermal effects of the fire hot gases for triangular ceiling shape with symmetrical and unsymmetrical shapes.
The model of industrial building is built for the usage by PyroSim fire-modelling program which is a typical industrial building dimensions reduced to one tenth, the initial parameters are kept constant to investigate the change of ceiling shape in fire behavior using three different positions.
