Abstract:

In order to eliminate existing fire hazards of old industrial building regeneration projects, improve their safety, and to promote development of resilient cities, concept of fire safety resilience for these projects was proposed based on theory of resilience. Then, according to relevant norms and documents, a resilience evaluation index system was constructed from three aspects, absorption capacity, disaster adaptability and recovery capacity. In order to reduce influence of subjective factors, combined index weighting method was used to determine weights of indicators, and TOPSIS was adopted to evaluate their fire safety resilience. Finally, with regeneration project of Shaanxi Iron and Steel Plant as engineering background, four concrete examples were selected to evaluate and verify scientificity and effectiveness of the method. The results show that the absorption capacity and disaster resilience of regeneration projects are poor, which makes their fire safety resilience generally low. Implementing corresponding countermeasures proposed from these perspectives can significantly improve fire safety resilience of the projects.

Key words: old industrial buildings, regeneration projects, fire safety resilience, technique for order preference by similarity to an ideal solution (TOPSIS), resilient city, operation and maintenance period
