摘要
用长方体试件采用悬挂自由振动方式来测定轻骨料混凝土的阻尼比,研究了页岩陶粒混凝土阻尼比与强度、响应频率等参数之间的关系,并通过对粗骨料界面进行涂油弱化处理,测试处理前后轻骨料混凝土阻尼比变化情况,为研究混凝土界面与阻尼比之间关系打下了一定的基础.
Hanging cuboid specimen and free vibration method was employed to measure the damping ratio of lightweight aggregate concrete.The relationship between damping ratio and some factors,such as compressive strength and response frequency,was studied in this paper.Then the light aggregate was oiled to make the interface weak and the influence to damping ratio was tested.The results are helpful for studying the relationship between damping ratio and concrete interface.
