Abstract
This paper presents a study on the evacuation analysis in underground arcade. In this study, the effect of the exit with a windbreak door has been investigated by using evacuation simulation program (building EXODUS). Also, the simulation has included the impact of smoke, heat and toxic gases by fire simulation program (CFAST). The results were obtained for the conditions of without and with door of the two exit with 1,088 evacuation population. As a results, for non-fire evacuation, there was only a little difference of evacuation time for both conditions. However, for fire emergency evacuation, the evacuation time for the condition with door increased more 110 seconds than for the condition without door. When the auto door not opened, the evacuation time was increased more 670 seconds than for the condition without door. Consequently, in case of fire, the automatic door should be operating by the signal of fire detector and keep open when the fire accidents. To lead the evacuees well to the escape route the luminaries for an emergency exit sign have to be reinforced to the wall and floor around the exit.
