Research On Evacuation Behavior And Evacuation Strategy Based On BuildingEXODUS

Research on evacuation behavior is the basis of the entire evacuation field.Researchers at home and abroad have conducted extensive research on evacuation behavior.Based on the theory of fire safety engineering and behavior,this paper uses the method of questionnaire survey to collect the basic characteristics and psychological behavior characteristics of personnel,and uses SPSS data analysis software to analyze the correlation between two variables,personnel characteristics and personnel evacuation psychological behavior.Conduct a correlation study.At the same time,the research results of the questionnaire survey were applied to the formulation of the evacuation strategy,and the effectiveness of the survey was verified by computer simulation.In this paper,the evacuation behavior is taken as the research object,and the basic characteristics of the personnel and the stress behavior in the pre-evacuation stage are investigated.Basic characteristics of people include age,gender,education level,fire and acting experience.Evacuation behaviors include behavioral responses to alerts,whether the behavior of the people around them affects escape decisions,the influence of peers on their own evacuation behavior,and the redirection behavior of fire.Through the collection and collation of data,and the correlation analysis using SPSS data analysis software,the research results show that 85.9% of the personnel will immediately take the evacuation action when the staff informs the disaster on the spot,and immediately take the escape under the alarm bell alarm mode.The action is related to whether there is fire or evacuation drill experience and age;the higher the education level,the stronger the self-protection consciousness of the personnel;the credibility of the alarm information is the standard for the staff to judge whether to immediately make the evacuation action;the male is more willing to slow down To assist the companions to evacuate together.According to the questionnaire survey,85.9% of the personnel immediately took the evacuation action when the staff member notified the disaster on the spot.This alarm method has the highest credibility for the evacuated people.In order to explore the effectiveness of this alarm mode to improve evacuation efficiency,this paper takes a comprehensive office building as the model carrier and uses the BuildingEXODUS evacuation simulation software to carry out computer simulation research.Firstly,the personnel’s familiarity with the emergency exit is simulated.The results show that the lower the familiarity of the people with the building,the earlier the evacuation bottleneck occurs;when the evacuation processproduces the evacuation bottleneck,the evacuation balance and the continuous index value Controlled by evacuation bottlenecks.When the density of the building is low,the balance and continuity are greatly affected by the distribution of personnel;when most people only understand and choose the main exit evacuation,they only improve the performance of the secondary exit and the building evacuation components on its path.It does not make much sense to improve the overall evacuation performance.On this basis,the staff’s notification of the disaster on the spot was used as the evacuation strategy of human intervention,and the simulation analysis of five different working conditions was carried out.The results show that the building is managed in a sub-area.In the emergency state,the staff informs and guides the evacuation of the area in charge,which can reduce the average pre-evacuation time by 40%,and the total evacuation time is greatly reduced.It is confirmed that the evacuation strategy under human intervention can be greatly reduced.Improve evacuation efficiency.However,while reducing the overall pre-evacuation time,the stairway confluence area will have an evacuation bottleneck earlier.Therefore,it is necessary to strengthen the management of evacuated people by avoiding high-density human flows formed in a short period of time and causing secondary disasters such as trampling.The alert method for the staff to inform the disaster on the spot is essentially a kind of disaster information transmission between the evacuated people.Therefore,the paper simulates the role of information transmission in the evacuation process,and the effectiveness of the human intervention evacuation strategy is carried out.Supplementary verification.The results show that the degree of information exchange between personnel has a great relationship with the density of personnel and the distribution of personnel.In the whole evacuation process,individuals trapped in the information occlusion environment are more difficult to obtain disaster information in time,resulting in delayed evacuation and even evacuation.failure.The way the staff informs the disaster on the spot can effectively ensure the comprehensiveness of information transmission.
