为研究钢筋混凝土梁在不同高温作用下的截面温度分布情况，采用自制高温电热炉和温度采集系统，对3根钢筋混凝土梁进行三面加热试验，实测了3种不同加热工况下梁截面各测点的升温曲线。通过试验数据的对比分析，得到了梁构件在高温作用下内部热传导和温度场分布规律，为分析高温下结构的受力性能提供参考依据。

@@@@For the research of temperature distribution in the section of reinforced concrete beam under different high temperatures,the experiment measured the temperature-time curve of different section point under three heating modes by the means of three surface heating test on the three reinforced concrete beams,using the self-made high temperature electric heating furnace and temperature acquisition system. Through the comparative analysis of the test data,the laws of internal heat transfer and temperature field distribution of the beam element at elevated temperature were summed up,which provide reference to the analysis of mechanical properties of the structure under high temperature.
