【摘要】 为了研究全景画馆画布的燃烧特性、火灾增长特点及对人员安全疏散和画布上方钢结构的影响,进行了油画布原布和涂油彩画布的竖向燃烧蔓延实验,用性能化消防设计的方法、运用FDS火灾模拟软件对全景画馆火灾进行模拟。结果表明:全景画馆画布火灾燃烧的蔓延速度较快,油彩会促进油画布的竖向蔓延速度;油画布原布火焰前锋在垂直方向的传播速度可表示为vf=(8.3~8.8)t0.32,而涂油彩油画布竖向火蔓延速度可表示为vf=7.576t1.065。全景画馆火灾模型为极快速发展的t2更多还原

【Abstract】 Vertical combustion tests were carried out to investigate burning behaviors and fire development characteristics of canvas,research the fire influence on safe evacuation and steel roof in a panorama museum.FDS software was used to simulate fire development in a panorama museum based on fire performance-based design concepts.Tests results show that the flame spread speeds of the canvas is very fast,and is promoted by the toner; the spread speed can be expressed as v f= (8.3 ~ 8.8)t0.32 for the original canvas,and as v f= 7.576t1.065 for the canvas with toner.The fire develops as the extremely fast t2 fire in the panorama museum更多还原
