Abstract: In order to evaluate the fire safety resilience level of the old industrial building reconstruction project, analyze the existing safety risks such as inadequate building fire performance, old fire control system, aging pipeline equipment and so on, the fire safety resilience index system was constructed from the four characteristic elements of resilience: robustness, redundancy, intelligence and efficiency, and the fire safety resilience evaluation model based on entropy weight method- extension cloud was established to quantify the influence degree of each index and classify grades. Taking an Xi'an textile factory reconstruction project as an example, the paper analyzes the weak links of fire safety and puts forward reasonable resilience improvement strategies, which provides reference for fire safety optimization of such projects.
