摘　　要：对中原地区880户住宅进行调查统计,得到1770组卧室信息有效数据,在荷载统计的基础上,进一步抽取样本,利用FDS软件模拟得到了活动火灾荷载下样本卧室的空气升温曲线。结果表明:火灾作用下室内环境温度受火灾荷载密度、通风条件、建筑形式等多种因素的制约。ISO834标准升温曲线与环境实际升温有较大差别,采用卧室火灾模拟升温曲线可以较真实地反映活动火灾荷载作用下卧室的空气温度变化情况,这为住宅建筑的高温分析和进一步抗火设计提供了参考依据。About 880 dwelling houses were investigated in Central Plains region, and 1, 770 groups of data were obtained. On the basis of the results of investigation, the fire simulation software （ FDS ） was used to calculate the practical heating up curves of sample bedrooms. The results indicate that environmental temperature is influenced by many factors, such as fire load density, draft condition, architectural form, and so on. The ISO834 heating up curve is largely different from true temperature field, and yet the simulation heating up curves work well. All of the results provide a theoretical foundation for the similar residential building structures＇ fire resistance design.
