Experimental Investigation on Temperature Distribution of Reinforced Concrete Beam

Abstract:

To research the temperature field distribution of concrete beams, experiments on fire resistance of 6 reinforced concrete simple-supported beams were completed. Test results indicate that: the trends of the temperature field distribution in each section of beam are the same, but the difference of the values in each section is large; the larger section of beam is, the higher temperature of beam surface and the more slowly the heat transfer to the internal of beam, which shows the increase of concrete cover thickness can improve fire resistance of beams; After the fire, the gradient of temperature field distribution is very serious in the internal of beam; the higher the temperature of the fire, the bigger damage of reinforced concrete beams is.
