This paper presents results from a push-out experimental study on the effect of temperature on the bond-slip of steel and concrete.11 SRC column specimens

under different constant high temperature

are tested by using home-made fire test furnace to evaluate the bound strength in 20

00 ℃ temperature range.Data from test indicate that the ultimate slip and the residual load of SRC specimens drop with the increase of temperature.The fast drop happens in 20

00℃

the slip load and residual load of SRC become slower after 200 ℃.The number of crack increases from 20 ℃to 600 ℃.The initial slip is higher than that of specimens at room temperature.The initial slip range is from 2.5mm to 3mm in different high temperatures.
