中原地区住宅卧室活动火灾荷载调查与统计分析

Survey and statistical research on live fire loads of residential bedrooms in Central Plains region

以河南省郑州市及该省一些中小城镇为代表,对中原地区880户住宅进行了调查统计,得到了1770组卧室面积及家电家具重量、材质等数据信息,并从中随机抽取70组计算出卧室活动火灾荷载,进行了统计分析。结果表明,基于住户个人喜好和家具材质的不同,卧室活动火灾荷载密度差异较大,但一般卧室活动火灾荷载密度服从对数正态分布。

About 880 dwelling houses were investigated in Zhengzhou City and some mid to small cities and towns in Henan Province. According to the results of investigation, 1 770 groups of data were obtaine, which containe the information on bedroom area, household appliances＇ and furniture＇ s weight and material property.
