A Method of Evaluating the Design of Evacuation Based on the Using Rate of Unit Effective Evacuation

Yang Jianpeng,Zhang Heping,Pan Zheng,Ma Ning,Jiang Weicheng

Strategic Study of CAE 2006, Volume 8, Issue 5,   Pages 94-97

Abstract:

During designing a building, the design of evacuation is very important.The rationality of the design of evacuation determines whether people can evacuate from buildings.But the existing criterion does not relate to how to evaluate rationality of various designs of evacuationThis paper advances a method which uses the using rate of unit effective evacuation width as the majorAnd this method can give advices to adjust the design to profit personal evacuation.
