Risk Factors of Post-earthquake Fire for Constructions Using the Analytic Hierarchy Process Approach

Urban area is always gathering huge population and different kinds of activities. Once there is any disaster, it would be very possible to have unrecoverable damage. For the post-earthquake fire in constructions, it would caucus damage not only in civilians' lives but also property. Therefore, it becomes an important issue for reducing the damage and casualties in post-earthquake fires. By considering the factors and managing execution for post-earthquake fire in constructions, this research is collecting the statistical data about the experts' opinion, then using Analytic Hierarchy Process (AHP) to analyze, and finalizing the construction of potential risk factors in post-earthquake fires. The five indicators after weighted in all the dimensions are "Well installation of automatic sprinkler equipment", "The application of flame retardant materials", "Unbroken structure of planning fire preventing zone", "Closing of fire doors", and "Execution of fire preventing management". The study result is very close to the potential risk factors of post-earthquake fire from current studies. It shows the relevant factors and the weight constructed by this research are compliant with current situation.
