Study On Fire Protection Design Of Net Buildings

Along with the raising of economy and cultural living standard and the quick development of science and technology, internet has brought shortcut and convenient service to work\study and life of the public. At the same time, the commercial place, named net building, which offers the internet services to the public through computers etc. equipments, emerge as the require in social demand.However, along with the quick development of the net building fire, it becomes one of the fire types that occur frequently in our country. Because of all kinds of reasons, such as consuming plenty of electric, centralizing of things can burn and property, and hard management of people, the building fire can often cause the accident of significant personal casualties to occur. Therefore, how to keep the net building fire away the public becomes a problem that should be solved urgently.Aiming at the present situation that the net building fire problem research lacks in domestic and international, this paper especially study on the important factors, which the crowd evacuation and the different impactions of smoke spreading.Firstly, this paper has analyzed the development of the net building and the influence to people's life; though comparing carefully of the characteristics of this kind of fire. Secondly, this paper has carried out further discussion for the problem of existent net fire through the case analysis and investigation on-the-spot; made some design methods for the net building from the angle of building fireproof design. Thirdly, this paper has simulated the net building fire using computer simulated software FDS and CFAST; calculated the problems of people evacuating and smoke spreading in the net building. Finally, this paper has verified the results that got from above.In the research of this paper, through investigation, invitation and analysis, plenty of bas in data and simulated data have been gotten. These data can be utilized when the building design specification and the net building design should be revised. Various study methods adopted in this paper can offer references for the fireproof problem research of the special building in the future. So this paper has certain reference value for realizing the special building fireproof design research of our country, and has important meaning for reducing the personal causalities in the net building fire, maintaining the society steady, and guaranteeing the continued development of socioeconomic.
