火灾下混凝土简支板等效火灾荷载的简化计算

The simplified calculation of equivalent fire load of concrete simply supported plate exposed to fires

根据热传学原理,得出高温下钢筋混凝土板截面温度场的分布,计算出火灾下钢筋混凝土简支板极限抗弯承载力,得出钢筋混凝土简支板的等效火灾荷载,为火灾下钢筋混凝土极限抗弯承载力的计算提供了方便。

According to the principles of heat transfer,the result of reinforced concrete slab s section temperature field is gained,calculating it s flexural capacity limit obtaining,obtains the equivalent fire load of the reinforced concrete slabs,providing a convenient way to calculate the flexural capacity limit of the reinforced concrete slabs.
