受限空间建筑火灾蔓延影响因素对比试验研究OA北大核心CSTPCD
Comparative experimental study on factors affecting fire spread in enclosed buildings
为观测受限空间建筑火灾蔓延时空演化规律,了解受限空间建筑火灾蔓延过程,建造了一座二层2x2跨的钢框架结构建筑,其中在一层设置四个房间,采用木垛作为火荷载开展受限空间建筑火灾蔓延试验.考虑火荷载、分隔构件、开口程度3个因素,共设置4种工况.试验中采用摄像机观测火灾蔓延过程,采用热电偶记录建筑内部空间温度场,基于耗氧法记录受限空间建筑火灾蔓延热释放速率.结果表明:火灾过程中火灾轰燃前持续时间较长,占火灾蔓延前持续时间的70%~85%,火灾轰燃后火势迅…查看全部>>
To observe the fire spread spatiotemporal evolution within enclosed buildings and explore the fire spread process,a two-storey 2x2 moment-resisting steel framed structure was constructed.Four rooms were arranged on the first floor,and wood cribs were employed as the fire load.Four distinct scenarios were considered based on fire load,compartment elements and opening size.During the experiment,the fire spread process was observed by the camera,the gas-phase t…查看全部>>
