混凝土阻尼比与劈裂抗拉强度的关系研究

Research on the Relations Between Concrete Damping Ratio and Its Splitting Tensile Strength

通过配制长方体试件并采用悬挂自由振动方式来测定卵石表面预处理前后的混凝土阻尼比,测试了混凝土和湿筛砂浆的劈裂抗拉强度,初步探讨了混凝土阻尼比与其劈裂抗拉强度间的关系,为研究混凝土界面强度与阻尼比之间关系打下了一定的基础。

Authors prepare some rectangular damping specimens and use hanging and free vibration method to measure the concrete damping ratio changes before and after coarse aggregate surfaces are pretreated, at the same time test the splitting tensile strengths of concrete and its wet mortar, discuss the relations between concrete damping ratio and its splitting tensile strength, laid a certain foundation in studying on the relationship between the concrete interface strength and its damping.
