摘要
某商业广场的建筑单体之间拟设置木结构景观通廊,为分析设置通廊的可行性,通过FDS火灾模拟和热传导计算,分析了增设通廊对人员疏散的影响、木构件温度场分布特征以及炭化特征,计算了火灾下木构件的承载能力。结果表明,设置木结构景观通廊不会影响火灾下人员疏散安全性,通廊的木构件会因高温而出现局部炭化,但仍可保持较高的承载能力。
A timber landscape corridor was proposed to be built between buildings on a commercial square.FDS fire simulation and heat conduction calculation was done,to analysis the practicability of the timber corridor.The impact of corridor on people evacuation,the distribution characteristics of temperature field and carbonization depth of timber components were analyzed.The bearing capacity of timber components was calculated.The results showed that timber landscape corridor will not have an adverse impact on the safety of people evacuation,timber components will maintain bearing capacity well,although localised areas of them will be carbonized.
