Vulnerability Assessment Model of Urban Commercial Complex under Fire Disaster Scenario

Combining the existing research results of vulnerability theory, the vulnerability theory is introduced into the fire safety field of urban commercial complex, and the concept of urban commercial complex vulnerability under fire disaster scenario is proposed.Based on the source of vulnerability, from the three aspects of personnel, equipment and environment, and further combined with the three elements of vulnerability structure (exposure, sensitivity, adaptability) to analyze the fire vulnerability impact factor.On this basis, the fuzzy comprehensive evaluation method is selected to establish a mathematical model for assessing the vulnerability of urban commercial complexes under fire disaster scenarios, Realize the determination of vulnerability level. Finally, with a certain urban commercial complex in Xi'an as an example,a vulnerability assessment was conducted by using the model. The results show that the results obtained by the application model are basically consistent with the actual situation, which further verifies the feasibility and practicability of the model.
