基于未确知聚类的高层建筑防火风险评估系统

目前，高层建筑的火灾防控难题一直未得到有效解决。针对高层民用建筑防火能力风险评估中评估指标获取不科学、指标体系差异大的问题，运用典型火灾事件分析法，结合《建筑设计防火规范》，科学获取影响高层建筑防火能力的12个主要不确定性风险因素，构建了更为科学的高层建筑防火能力风险评估指标体系。在此基础上，引入未确知聚类理论，构建了基于未确知聚类的高层建筑防火能力风险评估模型。并以8栋典型高层民用建筑火灾风险数据为例，进行实证分析。研究成果表明，该风险评估系统可行有效。研究成果可为高层民用建筑火灾风险防控提供一种新的方法和途径。

The fire risk assessment system for high-risebuildings based on unascertainedclustering method

Abstract: The fire prevention and control problem of high-rise buildings has not been effectively solved. Aiming at the problems of the evaluation indicators acquisition that is unscientific and the index system varies greatly in high-rise civil building fire risk assessment, the typical fire event analysis method was used in this study, and combining with the code for fire protection design of building, 12 major uncertainty risk factors affecting the fire prevention capacity of high-rise buildings were obtained, to build a more scientific fire risk assessment index system. Then the unascertained clustering theory is introduced to build a new high-rise building fire risk assessment model. And the fire risk data of 8 typical high-rise civil buildings were taken as examples to conduct empirical analysis. Study shows that the system is effective. The research results can provide a new way for the fire prevention and control of high-rise civil buildings.
