ABSTRACT
With the outbreak of COVID-19, the phenomenon of crowds has attracted much attention. To study the impact of fire on evacuation density of teaching building under epidemic situation, a university teaching building was simulated by FDS. The influence of smoke exhaust window opening on fire development was studied by analyzing the law of smoke, temperature and CO concentration, and the allowable evacuation time ASET of teaching building was obtained. Evacuation simulation using Pathfinder determines the required evacuation time RSET and analyzes congestion points, making evacuation improvements from two aspects reducing the proportion of people and planning evacuation. The results show that CO concentration is an important factor affecting the ASET of teaching buildings, and it can extend the ASET of teaching buildings when the top smoke exhaust window is open;The evacuation congestion points of teaching buildings are mostly concentrated in the classroom exit, the east corner of the passage, the corner of the stair platform and the corner of the west exit. Although reducing the proportion of people can achieve safe evacuation, it can not meet the needs of the evacuation density under the epidemic situation. Through further evacuation planning, it can not only meet the requirements of safe evacuation, but also reduce the evacuation density, which provides a reference for the safe evacuation of teaching buildings under the epidemic situation. © COPYRIGHT SPIE.
