In the event of a fire in a high-rise building, rapid evacuation through the stairwell is a very important factor in rapid evacuation. However, in the event of an actual fire, most of the occupants evacuate at the same time, resulting in a stay in the stairwell, reducing the evacuation speed. In Korea, conditions for buildings are created to evacuate quickly and safely while introducing performance-oriented designs to solve these problems, but there is no research data related to the evacuation speed due to joining in the event of vertical evacuation. Therefore, in this study, by analyzing the experiment conducted at W University in Japan, the density-speed relationship when staying in the staircase room was derived, and the regression equation was derived based on the results.
