高温下钢板与混凝土的粘结强度

Bond strength between steel and concrete in high temperature

型钢与混凝土的粘结是保证钢 混凝土组合结构构件正常工作的基础。本文通过高温状态下钢板与混凝土的力学性能,以及钢板与混凝土粘结性能的试验研究基础上,分析了在高温状态下,钢板与混凝土的粘结强度,比较了高温与常温下其粘结强度的大小,并给出了不同温度下钢板与混凝土的粘结强度的计算公式。为钢 混凝土组合结构构件的受力分析奠定了一定的基础。

The bond between steel and reinforced concrete is a fundamental factor to ensure the workability of steel reinforced concrete composite structures and members. In this article, on the bases of experiment research in mechanical property of steel plate and concrete under high temperature and bond between two materials, the authors analyzed the bond strength between steel plate and concrete under high temperature, compare the magnitude of bond strength in ordinary temperature with it in high temperature, provide the formula for calculating the bond strength between steel plate and concrete under different temperatures and the groundwork for analysis of steel reinforced concrete composite structure under load.
