建筑火灾荷载不定性参数统计分析
|
摘要
火灾荷载是反应房间内包含可燃物多少的参数,是研究火灾的基本条件。许多国家发布了火灾荷载的相关数据,我国有一部分火灾荷载的统计数据,但统计范围不大,且没有火灾荷载不定性相关参数统计分析,本文收集国内火灾荷载统计数据若干组,包括办公楼、住宅、宾馆、超市、商场、建材市场、展览馆等不同功能的建筑火灾荷载数据。对其进行K-S假设检验,得到火灾荷载统计数据满足极值I型分布。最后对统计数据进行荷载不定性参数统计分析,分别得到不同功能建筑的荷载不定性统计参数,为抗火设计提供参考。
Fire loads are the parameters that reflect the amount of combustibles in the room,and it is the basic condition for the study of the fire. The statistics of fire load have been published in many countries,and some statistics of fire load have been published in China,but the statistical range of the statistics is not large and there is no statistical parameters analysis of the fire load uncertainties. Therefore,this paper collects the statistics of fire load data in China in nearly 400 groups,including different functional buildings: office buildings,housing,hotels,shopping malls,building materials market,exhibition hall,supermarkets and so on. The K-S hypothesis test is carried out,and the statistical data of the fire load are obtained to satisfy the extreme value I distribution. Finally,the statistical analysis of load uncertainty parameters is carried out for statistical data,and statistical parameters of load uncertainties for different functional buildings are obtained respectively,it will provide reference for fire resistance designs.
