Performance Based Study On Egress Safety Design In High-rise Hotels

Building fire disaster is a kind of common fire which happens frequently than others, the fire of a building has an important and directly influence on people, it is also a deadly threat to people's life safety and property.Thus, it is always the focus of fire protection to expertise all over the world.In the past decade years, with the development of the social economy and the prosperous of building market, there are lots of high-rise buildings, especially high-rise hotels have erected in many cities, and at the same time , because of new building materials and products massively used, the building fire disaster has a growing tendency every year. This brings much difficulties to safety evacuation and fire protection and fire extinguish .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. 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 purpose of the study of people's evacuation is to improve the fire safety design and cut down the number of casualties .There are many successful experience in foreign countries, and the results will be used in fire safety design and the new code. This paper is based on the analyse of the properties of high-rise building fire and its harm to people, and human behavior in fire, discus the main factors which influence the egress safety.
