Abstract

In order to explore critical phenomenon of flashover during fire development process in restricted space of wooden stilted buildings, with a typical wooden stilted building in Guizhou province taken as an object, critical value of flashover was quantitatively analyzed by using mutation theory and numerical simulation software. The results show that flashover phenomenon of stilted buildings with timber structure features Swallowtail Catastrophe, and the critical temperature calculated by it is 951. 5 K while that calculated by numerical simulation is 953. 4 K, which is comparatively consistent with the former. It is also found that occurrence of flashover in confined space has little relation with external wind speed. © 2020 China Safety Science Journal. All rights reserved.
