Modeling fires in structures with an atrium in the FDS field model

Abstract

Modeling of dangerous fire factors is an important element in the system of modern fire safety assessment of buildings and structures. The paper presents a comparative analysis of the characteristics of the software system PyroSim. The verification of the fire model in the FDS program, which was performed on the basis of full-scale tests conducted by Professor Chau W.L., was analysed. The analysis of empirical and calculated data on modeling of fire in the atrium is made. The conclusion is made about the accuracy of simulation in the FDS program and the coincidence of the experimental data with the calculated ones.
