摘要
通过试验,对常温20℃及100~600℃高温后混凝土的力学性能进行了比较,研究和分析了不同温度后混凝土的抗拉强度及钢筋与混凝土黏结强度的变化规律,并在此基础上建立了高温作用后混凝土抗拉强度与黏结强度的推算公式,可为高温后混凝土结构的设计分析提供理论依据。
The mechanic tests of concrete at 20 ℃ normal temperature and from 100 ℃ to 600 ℃ high temperature were completed,The tensile strength of concrete and bonding strength between steel bar and concrete were analyzed.On the basis of the tests and analysis,the relationship between tensile strength and bonding strength of concrete subjected to high temperature was established,The conclusions can provide theoretic basis for the design and analysis of concrete structures.
