Evacuation performance design Book cover wholesale from building personnel safety aspects to consider , through considering various factors on the fire escape of personnel , the use of performance-based Book cover wholesale design methods to ensure the building fire personnel security, thereby preventing casualties. The performance of the Book cover wholesale design criteria are: smoke layer height and flue gas concentration reaches people cannot endure longer than the time required for safe evacuation .

Element fire performance of Book cover wholesale design is carried out from the building 's stability considerations , building components by analyzing reactions in the fire , the use of performance-based Book cover wholesale design methods to ensure the stability of the building structure fires , thereby preventing the collapse of buildings . Its performance-based criteria for the design Book cover wholesale : fire fire duration less than the time component .

5 Performance of Book cover wholesale domestic design application profiles

Since the 1980s, the British proposed a " performance-based fire safety design Book cover wholesale approach " (performance - basedfiresafety

design method, hereinafter referred to as performance-based fire design Book cover wholesale ) since the concept , Japan, Australia , USA, Canada, New Zealand and the Nordic governments have invested a lot of other developed countries actively engaged in research funding Book cover wholesale fire performance-based design techniques and methods research , South Africa, Egypt , Brazil and other developing countries also have to carry out research work in this area . Countries around the world are actively implementing performance-based design Book cover wholesale application of the method , and has made great achievements.

England in 1985 promulgated the first performance-based fire protection specifications, including performance-based fire code changes, the new specification " must build a security architecture" , but not in detail to determine how to achieve this goal.
