摘　　要：对足尺钢筋混凝土三跨连续板进行了恒载下中跨受火试验研究 ,全部火灾试验采用自行研制的火灾试验炉 ,试验结果表明炉子性能稳定、使用方便。通过试验 ,给出了钢筋混凝土连续板在高温下的变形、温度分布规律 ;A research about the full scale three span reinforced concrete continuous slabs with dead load under fire was carried out.The whole test made use of the self made fire test furnace which was reliable and convenient.From the test,the regularities of the deformation and the temperature distribution are presented, furthermore the characteristics of the internal force redistribution and their destroying features are analysed.

关 键 词：钢筋混凝土 火灾试验 连续板 温度 极限承载力
