Simulation Study On Emergency Evacuation Of Constructional Engineering Building Of Hebei University Of Science And Technology

In this paper,building safety evacuation design application of BIM is taken as the research object.And a BIM-based building evacuation model is developed to figure out the self-organization behavior and dynamics of the whole process,getting some valuable visual simulation results.Base on it,the study discusses the building design evacuation is safe,providing theory and practice basis for safe evacuation in the future.Related details are as follows:First,relevant basic theories such as BIM,pedestrian evacuation,as well as building safety evacuation design management are deeply discussed.Application advantages of BIM,operation process of computer simulation in studying building fire evacuation are concluded by analyzing its function features and evacuation characters.And also,current problems of building safety evacuation design management are pointed out clearly with the purpose of better system optimization.Second,given the data structure and transformation standard of building information model,Pathfinder is chosen as an associated software with BIM by comparing different computer simulation software.Therefore,this article discusses the possibility and technical conditions of application of both tools in safety evacuation design from main three aspect: specific building software,function benefits fire fighting technology involved.Thus,a BIM-based safety evacuation behavior pattern is developed in order to lay the foundation of further simulation.Third,a secondary school design is selected as a simulation building project to find out the evacuation effect in the worst situation,from the practice of fire fighting application.Under the premise,this research conducts an analysis of the occupants' evacuation behaviors and safety within the required safety egress time and available safety egress time.After that,the evacuation optimization scheme aiming at the teaching building project is put forward.In the meantime,some BIM-base evacuation suggestion are summed up for other similar engineering evacuation.
