Study Of Public Facilities’ Safety Evacuation Based On BIM

Large-scale public facilities are closely related to people’s lives, because of theevacuation efficiency and the stampede probability increases caused by the peoplegathered in public facilities, evacuation of personnel safety is becoming the fundamentalconsideration when public projects organize activities. An important means of carryingout the evacuation is building BIM technology. In recent years, the vigorousdevelopment of the BIM technology has brought new vitality to the safe evacuationof research. The application of BIM technology can not only provide comprehensive andaccurate information but also make the simulation environment more realistic.This thesis analysis the characteristics of evacuation complex adaptive system, andproposed the modeling framework for Cellular Automata based on Agent. According tothe various components of the framework, the paper analysis factors that affectindividual’s perception, decision, and behavior; and introduced the basic method draw ongrid modeling of environment space based on Cellular Automata. The simulation modelwhich can reproduce the reality of evacuation is of great practical description. Forlarge-scale public facilities control staff capacity simply according to the homogenizationof the occupant density, starting from BIM technology and make an Expo Center as anexample, to analyze simulation results by mathematical methods.The thesis obtains staff composition, evacuation speed, number of obstacles andlayout, the width and number of evacuation outlet factors such as changes impact staffcapacity; the maximum capacity member of the Expo Center in the safe evacuation of thepremise; and increase the capacity member by improve the evacuation of public placesconditions. Safe evacuation in order to optimize the evacuation process and improve theevacuation efficiency by design of building evacuation, the crowd system planning andmaintenance of group behavior, which has great impact to strengthen the safe evacuationof large-scale facilities and promote the application of BIM technology.
