基于灰色关联度的集对分析方法在高层建筑火灾危险性评价中的应用

为了对某钢管厂高层建筑进行火灾风险评估，基于高层建筑的防火、灭火设计要求，从防火系统、灭火系统、安全疏散和消防安全管理四个方面构建了高层建筑火灾危险性指标评价体系，并运用层次分析法确定了各火灾危险性影响因子的权重。根据集对分析的联系度模型对高层建筑进行火灾危险性评估，确定其安全等级。结合灰色关联度理论对差异度与同一度、对立度两组数据进行计算比较，选取绝对关联度大的值作为差异度系数i的值，从而可以确定各组联系度的值。根据联系度最大值所属的安全等级，确定了高层建筑的火灾危险等级为一般安全，结果与实际情况相符。

Application of set pair analysis method based on gray correlation in fire risk assessment of high-rise buildings

In order to carry out fire risk assessment on the high-rise building of a steel plant, based on the design requirements of fire prevention and fire fighting for high-rise buildings, an index evaluation system of fire risk in high-rise buildings was established from four aspects including fire prevention system, fire extinguishing system, safety evacuation and fire safety management, and the weights of each influence factor on fire risk were determined by using AHP method. The fire risk of high-rise building was evaluated based on the connection degree model of set pair analysis, so as to determine the safety grade. The difference degree was calculated and compared with two groups of data including identical degree and opposition degree by combining with gray correlation theory. The larger value of absolute correlation was selected as the value of difference degree coefficient , then the values of each connection degree were determined. According to the safety grade of maximum connection degree, the fire risk grade of the high-rise building was determined to be general safety, which was consistent with the actual situation.
