In this paper, a dynamic model of fire spread considering fire spread in both horizontal and Received in revised form vertical directions is described. The algorithms for simulating the fire spread process in buildings and 11 February 2011 calculating dynamic probability of fire spread for each compartment at each time step of simulation are Accepted 11 February 2011 Available online 5 March 2011 proposed. The formulae used in calculating the input data for the dynamic fire spread model are derived. The dynamic fire spread model can easily be applied for any building including high-rise buildings. Keywords: A detailed example of calculation of fire spread in a two-storey office building is described. Fire spread
