办公楼人员密集,火灾时人员疏散困难。在北京市共选取6栋办公楼进行火灾荷载的调查统计,对调查所得数据进行了拟合计算,确定办公楼活动式火灾荷载密度平均值为651.63MJ/m2,标准值为2057MJ/m2,所得办公楼火灾荷载数据不拒绝服从极值Ⅰ型分布,本文给出了分布形式,在此数据基础上进行了建筑性能化防火设计。
Dense office staff, fire evacuation difficulties. In Beijing, a total of 6 office buildings were selected for fire load investigation and statistics. The data obtained from the survey were fitted and calculated. The average fire load density of office buildings was 651.63 MJ / m2 and the standard value was 2057 MJ / m2. The fire load data of office building are not rejected obeying the extremum Ⅰ type distribution. This paper gives the distribution form, on the basis of this data, conducts the building performance fire protection design.
