(1.西安建筑科技大学 710055;2.青岛建筑工程学院 266033; 3.山东省建设厅)[提要] 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;分析了连续板的内力重分布和破坏机构的特点。
[关键词] 钢筋混凝土 火灾 火灾试验 钢筋混凝土 连续板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.
