Abstract
As building height is increased, more careful decisions about the required safe egress time is needed for evacuation. This study analyzed the influence of three training sessions on the vertical speed of evacuation in the high rise building. Evacuation experiments were done in a high-rise office building in Seoul, and we analyzed the vertical evacuation speed as a function of density using a camera. Controlled and uncontrolled total evacuation were compared using the Pathfinder simulation. The process of repeated training, changed the specific stair utilization rate from 6.3% to 39.5%. The vertical evacuation speed as a function of density was analyzed using the equation s = 1.004 ? 0.288D, which is very similar to the equation used in a different study. The total evacuation time of the special controlled total evacuation was reduced by about 25% compared to the simultaneous evacuation.
