Research On The Safety Evacuation Of Performance-based Fire Protection Design

Performance-based fire protection design is one of the research direction of the most forward position in present domestic and international fire protection scientific and technological field. Since the 80' s of last century, the developed countries have carried on a large amount of research work, making rich achievement and making corresponding performance-based building codes according to their national conditions separately. With the development of economy and science of our country, the current building codes demonstrate a lot of shortcomings that can not solve the appearing fire protection design problem of the super highrise and super large-scale buildings rationally, so it' s time to launch the research work on performance-based design and to establish our performance-based building codes according to our national conditions. At present, the performance-based design is still confined to the fire protection scientific and technological field , and isn' t well understood by the most achitects. It is disadvantageous for the development of performance-based design. So one of the purpose of this article is to play a role in casting a brick to attract jade in popularization of the idea.This article mainly includes four parts. The first part analyses some limitation and shortcomings in our current building codes;The second part introduces the concept of performance-based design,the overview of domestic and international research and the basic step and assessment of performance-based design;The third part is the research on the safety evacuation of performance-based design;The last part applies the method of performance-based design to analyse two engineering cases.
