AbstractIn order to investigate the structure behavior under travelling fire, the numerical simulation of a full-scale travelling fire test with wooden fuels was completed by using FDS. The fire development and the heat release rate (HRR) were obtained. The temperature information, including gas temperature in the smoke layer, column surface temperatures at different heights, steel beam temperature and concrete ceiling temperature, were calculated from the FDS simulation. Although the compartment was rather small, obvious differences in temperature of the upper smoke layer and the steel beam, caused by the travelling fire, were observed. The maximum gas temperature under the ceiling was close to 1000°C.
