Fire risk assessment for large-scale commercial buildings based on structure entropy weight method

Based on the fire characteristic and the maintenance of fire equipment in the large-scale commercial buildings, this paper proposed a fire risk assessment system for large-scale commercial buildings. The assessment system focus on evaluating the safety performance of the fire protection system in the buildings. Firstly, the index system of the assessment system was determined by on-site investigation and experts' suggestions. Secondly, the weight of each index was determined by the structure entropy weight method. Thirdly, the score rules were determined according to the regulations from the relevant laws and design codes. Finally, the score and the corresponding fire risk level could be obtained. Moreover, four large-scale commercial buildings in Chongqing, China have been taken as examples to calculate the values of the fire risk level by the proposed assessment system. In addition, the fire safety performance of the four buildings were analyzed.
