Description

In order to develop an evacuation simulation program that the fire safety manager of a building can easily utilize for effective evacuation and establish an appropriate evacuation plan in case of fire, it was tried to reflect the actual behavioral characteristics of the evacuees. To this end, a plan must be prepared to maximize the accuracy and completeness of the simulation program through real-scale evacuation experiments.
Evacuation simulation has a great influence on the actual evacuation time depending on the input value, but Korean building-related laws only stipulate the width of the corridor and stairs corresponding to the evacuation passage and the maximum distance from the living room to the stairway entrance depending on the use of the building. However, there is no regulation on the shape of the evacuation route inside the actual building, that is, the shape and angle of the intersection. Also, depending on the shape of the intersection, the occupant's choice of evacuation route changes and directly affects the evacuation time. Analysis through the shortest straight line distance from the living room where occupants are located to the stairway entrance is the most ideal evacuation activity using fragmentary evacuation lines, so there is a difference from the actual evacuation time of occupants in case of fire. Therefore, in order to improve the reliability of the currently used evacuation simulation, the main factors that can directly affect the actual evacuation are classified, and experimentally measured and analyzed values are reflected in the evacuation simulation algorithm to improve the quality of the building through evacuation simulation in the future. It will be possible to minimize the occurrence of errors in fire safety evaluation.
Major factors that can affect the evacuation of occupants in the event of a fire include reduced visibility due to smoke, whether fire-fighting facilities are installed and operated, the type of intersection, whether evacuation guides are placed, and bottlenecks in evacuation passages. In this study, in order to analyze the various behavioral characteristics of evacuees during a fire, an evacuation demonstration experiment plan was established in an evacuation model room and an actual building, and was used to analyze the behavioral characteristics of evacuees and RSET in case of fire.
