Assessment For The Fire Risk Of High-rise Building Based On FAHP-FCE Modes

In recent years, there are more and more high-rise building fire accidents occurred, which is not only brought great damage to property, but also caused serious casualties. Therefore, the research work of fire of high-rise building is also increasingly important. Fire safety assessment is one of the important content of the high-rise building fire research, which aims to take appropriate safety measures in order to achieve the purpose of reducing fire through the analysis of the level of the high-rise building fire safety.In this paper, the fuzzy mathematics principles will be introduced into the analytic hierarchy process, and the high-rise building fire risk assessment will be analysised by building FAHP-FCE model. Firstly, through reading the literature, the author will determine the high-rise building fire risk indicators system and each index’s weighting coefficient by analytic hierarchy process model, and through the establishment of Fuzzy Consistent Judgement Matrix to increase high-rise construction risk factors the right to re-sort the accuracy with reasonable, then present their views and recommendations of the important risk factors.Then, the author combine with the fuzzy comprehensive evaluation model, and model synthesis algorithm is improved to be more reasonable so as to get the membership vector. Finally, through the analysis of a typical case, FAHP-FCE model was applied to practice, and to verify the effectiveness and practicality of the model. The paper will also put forward its own views and suggestions in order to attract the attention of the concerned departments, and the model can be used as the basis of the analysis and evaluation of the high-rise building fires, effective guidance of the high-rise building fire prevention work, so that the incidence of high-rise building fires can be reduced.
