【摘要】：近年来,高层建筑火灾事故频繁发生,由于结构复杂,使用频繁,人员众多,具有更高的事故发生机率,不仅会带来巨大的财产损失,也造成了严重的人员伤亡。因此对于高层建筑火灾的研究工作也日益重要。防火风险评估是高层建筑防火研究的重要内容之一,本文以高层建筑为研究对象,旨在通过分析高层建筑在火灾风险防护上的等级,采取相应的安全措施,以达到减少火灾的目的。目前,对高层建筑火灾风险进行分析的手段很多,但是很少有将概率方法与模糊评价方法相结合的。本文将模糊数学中相关原理引入到层次分析法中,通过构建FAHP-FCE模型对高层建筑火灾风险进行评估。首先通过文献研究确定高层建筑火灾风险指标体系,并通过一系列筛选过程验证其合理性和实用性,然后运用层次分析法确定各指标的权重系数,并通过建立模糊一致判断矩阵来增加高层建筑风险因素权重排序的准确性,进而对重要的风险因素提出自己的看法和建议。确定评估指标体系各指标权重之后,笔者结合模糊综合评价模型,并选择改进的合成算法以得到更加合理的隶属度向量,得到了文章所需要的评估模型。论文最后通过典型案例分析,将FAHP-FCE模型应用到实践中去,验证了该模型的有效性和实用性。可用来作为高层建筑火灾风险评估的依据,有效指导高层建筑火灾防范工作,减少高层建筑火灾的风险损失。
[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.
