摘要: 对足尺钢筋混凝土三跨连续板进行了恒载下边跨受火试验研究,通过试验,了解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。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。Abstract: In this paper, a research on the reinforced concrete full-scale three-span continuous slabs under fire was carried out, which underwent the normal loading.From the test, the regularities of the deformation and the temperature distribution were presented, furthermore the characteristics of the internal force redistribution and their destroying features of the reinforced concrete continuous slabs were analysed.The self-made fire-test furnace was used for all the tests, which is reliable and convenient.
