Abstract
The assessment of evacuation characteristics by using an evacuation model is highly important to improve the evacuation safety of buildings. Thus, recently, the radiation repulsive force model was developed for improving the reliability of the simulation results by considering the interaction between fire and evacuation. However, additional experimental study is required for improving the practicality of the radiation repulsive force model, because the threshold value of radiative heat flux is arbitrarily specified and the individual of the evacuees are ignored in the radiation repulsive force model. Therefore, we performed an experimental study for improving the practicality of the interaction between evacuees and fire. Also, the distributions of the threshold value of radiative heat flux and the individuals of the evacuees are applied on the radiation repulsive force. Then, the modified radiation repulsive force is added on Helbing’s social force model, and modified social force model is named as BR (Bae and Ryou)-radiation model. Evacuation characteristics of the BRradiation model are compared with the social force model and existing radiation repulsive force model. As a result of analysis, it is identified that the reliability and practicality of the simulation results estimated by BR-radiation model are more improved than the existing models.
