BIM-based Virtual Simulation of Fire Emergency Evacuation for College Library
College library,with high flammability and population density,is typical enough that a fire broking out in it would set off unanticipated campus chain effects,and it is necessary to analyze the personnel evacuation for college library on fire.Firstly,this study made a comprehensive influence factors summary by literature review.Then,a questionnaire was designed and distributed to some college students nationally to understand the overall cognitive level of college students to fire evacuation in library.And then,this paper concluded the key influence factors which are escape space change,the familiarity of escape sign locations,emotional contagion,and counter flow behavior respectively.Finally,based on Agent model,BIM technology,Pathfinder software and Pyrosim software,a university library was modeled and simulated,and the influence of the four factors on the evacuation process was quantitatively analyzed through comparative experiments.The simulation results showed that all the four factors could extend the evacuation time and affect the security performance of college library in different degree,among which the counter flow behavior was the most prominent factor especially;and based on the experimental data,corresponding improvement measures can be proposed as references for fire emergency management of university libraries in China.
