【摘要】：近年來,高層建筑火災事故頻繁發(fā)生,由于結構復雜,使用頻繁,人員眾多,具有更高的事故發(fā)生機率,不僅會帶來巨大的財產(chǎn)損失,也造成了嚴重的人員傷亡。因此對于高層建筑火災的研究工作也日益重要。防火風險評估是高層建筑防火研究的重要內容之一,本文以高層建筑為研究對象,旨在通過分析高層建筑在火災風險防護上的等級,采取相應的安全措施,以達到減少火災的目的。 目前,對高層建筑火災風險進行分析的手段很多,但是很少有將概率方法與模糊評價方法相結合的。本文將模糊數(shù)學中相關原理引入到層次分析法中,通過構建FAHP-FCE模型對高層建筑火災風險進行評估。首先通過文獻研究確定高層建筑火災風險指標體系,并通過一系列篩選過程驗證其合理性和實用性,然后運用層次分析法確定各指標的權重系數(shù),并通過建立模糊一致判斷矩陣來增加高層建筑風險因素權重排序的準確性,進而對重要的風險因素提出自己的看法和建議。 確定評估指標體系各指標權重之后,筆者結合模糊綜合評價模型,并選擇改進的合成算法以得到更加合理的隸屬度向量,得到了文章所需要的評估模型。論文最后通過典型案例分析,將FAHP-FCE模型應用到實踐中去,驗證了該模型的有效性和實用性�？捎脕碜鳛楦邔咏ㄖ馂娘L險評估的依據(jù),有效指導高層建筑火災防范工作,減少高層建筑火災的風險損失。
[Abstract]:In recent years, fire accidents occur frequently in high-rise buildings. Because of complex structure, frequent use and large number of personnel, there is a higher probability of accidents, which will not only bring huge property losses. The fire risk assessment is one of the important contents of the fire prevention research of high-rise building. This paper takes high-rise building as the research object. The purpose of this paper is to analyze the grade of fire risk protection of high-rise buildings and take corresponding safety measures to reduce fire. At present, there are many ways to analyze the fire risk of high-rise building, but few combine the probability method with the fuzzy evaluation method. In this paper, the relevant principles of fuzzy mathematics are introduced into the Analytic hierarchy process (AHP). The fire risk of high-rise building is evaluated by constructing FAHP-FCE model. Firstly, the fire risk index system of high-rise building is determined by literature research, and the rationality and practicability of the index system are verified by a series of screening processes. Then the weight coefficient of each index is determined by AHP, and the accuracy of weight ranking of risk factors of high-rise building is increased by establishing fuzzy consistent judgment matrix, and then the author puts forward his own views and suggestions on the important risk factors. After determining the weight of each index in the evaluation index system, the author combines the fuzzy comprehensive evaluation model and selects the improved composition algorithm to obtain more reasonable membership vector. Finally, the FAHP-FCE model is applied to practice to verify the effectiveness and practicability of the model, which can be used as the basis for fire risk assessment of high-rise buildings. Effectively guide the fire prevention work of high-rise building, reduce the risk loss of high-rise building fire.
