Research On The Performance-based Fire Protection Design Meothed And Theory Of Buildings And Demonstration Engineering

Along with the development of social economy and the rapid advance of science and technology of building, the public buildings of new design concept and configuration emerge constantly in big city, especially developed city, and becomes characteristic sign buildings of city. The plenty of appearances of these new buildings have put forward huge challenge to the actual fire protection design standard and method of buildings now. The prescriptive fire protection design standard and method of buildings can not satisfy the requirements of fire protection goals of modern buildings more and more, and have also restricted the development of building art and building form variation greatly. Therefore one kind of more safe, reasonable and new fire protection design method of buildings are needed urgently to be established. So performance-based fire safety design method emerges under this kind of condition.Performance-based fire safety design method has become the focal point of research and development in lots of countries since it appeared. Now, many countries have carried out plenty of research works about performance-based fire safety design, and have gotten huge achievements. However, our country is 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.The paper's background is building fire protection measures in the ancient times in our country. The current actual development level fire protection safe engineering of our country and fire protection design standard is this research's basic starting point. Faceing building fireprotection design and assessorand and related people, on the foundation of domestic and international plenty of related datas and document, combining project practice experience, according to present condition of performance-based fireprotection design development and the characteristic of modern building, the paper elaborates and discusses background, advantage, concept, basic frame and step of performance-based fire protection design and ralated theory. And itnAbstracthas made thorough discuss about how to realize performance-based fire protection design about profection and control of smoke, water fire extinguishing system, person safety evacuation and fire safety assessment method and so on. At the same time the paper make preliminary research about the models related side of fire safe. According to two demonstration projects of domestic and foreign performance-based fire protection design, some problems in design process that should be noticed are gone deep into careful discussion. Finally the paper has given some suggestions about how to realize transformation from current prescriptive fire protection design method to performance-based fire protection design method in our country.This paper offer technology foundation for establishment of performance-based fire protection design method and regulation suitable for the national conditions of our country. In the long term, the related theory and method of performance-based fire protection design in this paper can promote to implement the performance-based fire protection design of our country to go on , and also has offered some way of thoughts for the study for analysis and design deep into further. At the same time, it has also been a certain reference role for performance-based fire protection design regulation that develops our country in the future.
