摘要本文利用火灾荷载密度分析法对某综合性商业建筑危险度进行了评估分析。调研区域为该建筑火灾荷载密度较高的典型场所，这些区域分别为：商店（服装类商铺，生活用品类商铺，家电类商铺），百货公司，厨房，就餐厅。根据计算分析结果得到：该建筑典型区域的火灾荷载密度分别为服装类商铺573.62MJ/m2，家电类商铺369.16MJ/m2，生活用品类商铺402MJ/m2，百货公司918MJ/m2，厨房421.90MJ/m2，就餐厅235.70MJ/m2。通过数据并分析得出该建筑的火灾增长因子为0.04689KW/m2s2。根据火灾增长因子预测了该建筑发生火灾时将形成快速火的蔓延方式。同时，根据火灾荷载密度数据，火灾增长因子评估得出该建筑属于火灾危险度较高的建筑。21855

Title Use of fire load density analysis to assess
Comprehensive commercial building fire risk
Abstract
In this paper, by the use of fire load density analysis ,we studied the risk of comprehensive commercial buildings. The research area is typical places of high fire load density. These areas are clothing shops，Daily necessities shops, Appliances shops, Department stores, kitchen and restaurant. According to the research analysis, it can be seen that the building fire load density of clothing shops is 573.62MJ/m2,,Daily necessities shops is 402MJ/m2,Appliances Shop is 369.16MJ/m2, Department Store is 918MJ/m2,,kitchen is 421.90MJ/m2 and restaurant is 235.70MJ/m2.By comparing literature survey, reference data, we found the building's fire growth factors, which is 0.04689KW/m2s2. According to fire growth factors, we could predict the way of the fire spreading. Simultaneously, According to the fire load density data and Fire growth factor, we think that the building is a member of high fire risk buildings.
