Study On Fire Protection And Safety Evacuation In High-rise Building With Atrium

With the development of social economy, rapid advance in the science and technology of building and the prosperity of building market, high-rise buildings spring up quickly in many cities of our country. Especially those of new design concept emerge constantly and become the symbolic buildings of cities.With a lot of new structure and materials used in the development of high-rise buildings with atrium, the tendency of fire disaster on the rise, causing many difficulties to safety and evacuation and presenting a huge Challenge to the fire protection design method.Life is precious, the main focus of the fire science and technology is the human beings life and the most important of the study is the egress safety of the people. Based on the analysis of the architecture design to protect the safty of building.Performance-based fire safety design method has become the focal point of research and development in lots of countries since it appeared. Now, many counties have carried out plenty of research works about performance-based fire safety design, and have gotten huge achievements. However, our country is still blank on a lot of aspects of performance-based fire safety design including theory and application. So we must strengthen performance-based fire protection design theory and method of buildings, which is particularly important.. At present, the study of the fire safety evacuation in the world mainly focus on: (1) the importance of the model of egress and the ability of modeling predict A obvious tendency of the study is that there will be more behavior details included in the model in the future; (2) the influence of the smoke and its toxicity to people which focus on the study of the influence of toxic gases such as carbon monoxide to people who exposed in fire, the test of the visibility of directional and exit signs, the behavior of the occupants in fire and the time they response to the fire; (3) the application of the evacuation model in fire safety design, the constitute of Performance-based Code and building evaluating.The safety evacuation of high-rise buildings is one of the most important parts of architecture design. Compared with the ordinary traffic organization. The subject the safety evacuation research studies and people's in case of fire, behavior are different. The objective of safety evacuation design is there toguarantee that people inside the building can leave in the shortest time through a safe route under the comparatively complex situation.Based on the analysis of the fire properties of high-rise buildings with atrium, human behavior reaction to the fire and the factors influencing personnel safety evacuation, and combined with the building plane and space, the paper aims to illustrate in detail the aim, the requirements and the corresponding technology measures of the personnel safety evacuation design in high-rise building with atrium. The prescriptive fire protection design and the performance-based design are adopted.
