Research On Identification Of Fire Risk Pivotal Parts Of Large-Scale Emporium

In recent years, large-scale emporium fire has always been one of the focuses of attention, and identification, analysis, evaluation and control of risk is the main means of minimizing the losses. It's important that we identify the fire risk pivotal parts then take rational measures to realize losses minimum. The article bases on the basic of comprehensive realization of fire risk assessment methods, then with the several problems of current emporium fire risk assessment and the uncertainty of FDS fire simulation software when setting up fire scenarios, the method of identification of fire risk pivotal parts is put forward. It's that we will make identification of fire risk pivotal parts as a theoretical basis for the researches of large-scale emporium fire.The article firstly makes use of the improved Gustav Fire Risk Method to analyze the fire risk pivotal functional areas, and then the pivotal functional areas are divided into several units, making use of fuzzy comprehensive evaluation method to determine the fire risk rating of every unit. Large-scale emporium is always structurally complex, it can be seen as a complex system, due to its integrity and relevance properties, the ultimate fire risk pivotal parts are not only high fire risk of themselves, but also should be the ones which can affect other units and even the whole functional area, this article makes use of the ISM to analyze the effects among the units. Therefore, the large-scale emporium's fire risk pivotal parts are the ones with high fire risk, at the same time, the ones that affect other units seriously and even the whole functional area greatly.Finally, it applies the method which this article established to a large-scale emporium. At the same time, it makes use of FDS fire simulation software to validate the results, the conclusions of simulation is in accordance with the calculation results.
