摘要

利用自制的火灾试验炉进行了11个型钢混凝土试件在恒高温下的推出试验。重点分析了型钢加载值与滑移量之间的关系、试件裂缝及其发展特征等内容。结果表明:随着试验温度的升高

型钢混凝土的极限滑移荷载与残余荷载相对于其在常温下的数值均有大幅下降

在20200℃时下降最快

200℃之后滑移荷载的下降趋势较为平缓。随着试件所受温度升高

加载过程中出现裂缝的部位增多。试验中高温下试件的初始滑移量高于常温下试件的

随温度的变化其在2.53mm范围内波动。

Abstract

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.
