Design Of Evacuation Stairs In Primary School Teaching Building Based On Evacuation Simulation

With the full realization of compulsory education in China,education resources are gradually balanced,the number of primary school students is growing,and the number and scale of primary school teaching buildings are also expanding.In order to meet the needs of today’s education,the functions of primary school teaching buildings in China are increasingly complex.Its architectural space has rich functions,complex traffic and dense crowd,which bring great challenges to the safety of public space.A large number of children are limited in a relatively limited space.Children who are not mature physically and mentally are prone to large-scale casualties in the process of evacuation in emergency.At the same time,the evacuation staircase is the most "bottleneck" in the evacuation process,because of its special structure,it is easier to induce danger.Therefore,improving the evacuation efficiency of children in the staircase area of primary school teaching building is an important content to be studied.The purpose of this paper is to study the influence of different forms of evacuation stairs in primary school teaching building on the evacuation efficiency of primary school children in the stairs,extensively investigate and summarize the forms of each part of the evacuation stairs in primary school teaching building,and establish different forms of space models of each part of the stairs in primary school teaching building under different evacuation conditions,Through many simulation experiments,this paper makes a detailed comparative study on the different forms of the components of the evacuation stairs in primary school teaching buildings,illustrates the relationship between the different forms of the evacuation stairs and the evacuation efficiency,and sums up the "advantage forms" of the components of the evacuation stairs in primary school teaching buildings.At the same time,combining with the actual situation,this paper puts forward some suggestions under different conditions,The optimization strategy of the components of the evacuation stairs in primary school teaching building.The purpose of this study is to supplement the design theory of evacuation related content of primary school teaching building,and provide part of technical and theoretical support for building fire protection and emergency decision-making analysis.In this study,the forms of evacuation stairs in primary school teaching building are divided in detail,and children of different ages are used in the experiment,which ensures the scientificity and effectiveness of the experimental results.At the same time,in the process of simulation experiment,the form of evacuation stairs in primary school teaching building is studied from the perspective of evacuation efficiency for the first time,and the design concept of "advantage form" of evacuation stairs is proposed based on the evacuation efficiency,which provides a new idea for the design and Research of traffic space in primary school teaching building in the future.
