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.
