Application of Analytic Hierarchy Process in Safety Assessment of Reinforced Concrete Structures after Fire Disaster

Jia-Jie Cui, Jun Deng, and Xiao-Da Li
Abstract—Many factors could affect the safety of reinforced concrete (RC) structures after fire disaster. Quantitative assessment of the safety risk of RC structures after fire remains a major challenge for disaster prevention and mitigation. In this paper, Analytical Hierarchy Process (AHP) was applied to evaluate the safety risk of RC structures after fire qualitatively and quantitatively. Firstly, three aspects-materials, geometries and functions were considered for ten safety evaluation indicators. Afterwards, the fire risk assessment model for RC structures was established and the model was used for a case study. Simultaneously, a workshop after fire damage in Jiangmen city was taken as an example and the AHP was applied to estimate the workshop structural safety risk. It is concluded that the evaluation results obtained by the AHP are in good agreement with the field identification results, which indicates that the AHP is applicable for safety risk assessment of RC structures after fire. The safety evaluation results based on the AHP can provide a reference for structural rehabilitation or demolition after fire, which is significant in fire disaster prevention and reduction.

Index Terms—Analytic hierarchy process (AHP), fire, safety risk assessment, RC structures.
