摘要
对北京地区的普通住宅进行了活动式火灾荷载的调查统计,并采用课题组前期理论研究成果进行了数据分析,确定活动式火灾荷载密度标准值为1197.17MJ/m2。通过对卧室、客厅、厨房火灾荷载值的分别计算可知,卧室的火灾荷载密度最大;通过对不同可燃物在可燃物总值中所占比例的计算,发现木材在住宅中是主要的可燃物;另外通过计算确定建筑物的活荷载与火灾荷载之间的比例分布也不拒绝服从极值Ⅰ型分布,其标准值为22.92。
There was a live fire load investigation analysis about Beijing residential building,foe which pre-theoretical research results of our group were used to analyze data, and the characteristic value of the live fire load density was 1197. 17MJ/m^2. Through the calculation about the bedroom, living room and kitchen, we can see that the bedroom fire load density is the biggest. The calculation of proportion of the different combustible thing value in the total combustible thing value indicates that the wood in the house is the main combustible thing, and that the distribution of the ratio of the building live fire load to the live load does not refuse to obey the distribution of extreme-Ⅰ,and the characteristic value is 22. 92.
