Abstract

This work presents numerical investigations of the thermal behaviour of fire resistant multilayered structure consisting of two steel sheets, gypsum plate and stone wool layer. Simulation was performed using SolidWorks^® Simulation software. The numerical simulation results were compared with experimental data obtained from the fire resistance test. The simulation results were found to be in good agreement with experimental results. It is shown that thermal behaviour of such multilayered structures can be investigated numerically, thus avoiding costly and time-consuming laboratory experiments.
