摘要
为了给建筑构件的耐火性能分级，必须要了解建筑构件的耐火时间。确定钢筋混凝土梁耐火时间以往只能通过耗资巨大的耐火试验。本文在一系列试验研究的基础上，建立了各种数学模型，提出一种分析法，采用计算机预测钢筋混凝土梁的耐火时间。这种方法的优点是能确定构件在实际火灾中的耐火性能。
It is necessary to determine the fire endurance of building compartments in order to classifytheir fire-resistance rating. The fire endurance could only be obtained by a standard fire-resistancetest in the past, which is rather costly. In this paper, on the basis of a number of fire tests andvarious mathematical models, an analytical method for predicting the fire endurance of rein forcedconcrete beams by a computer program is put forward. The advantage of this method is that it canpredict the fire endurance of building compartment exposed to real fire.
