摘要
配制了几种混凝土,用自由衰减法测试了它们的阻尼比,从混凝土周期荷载作用下的力学现象、粗骨 料界面、混凝土含水量、粘弹性材料含量等方面分析了混凝土阻尼产生机理。
Some classes of concrete were made up. Free vibration method was employed to measure the damping ratio of the concrete. The damping mechanisms of concrete were analysed, from these respects of mechanics phenomenon in period loading, coarse aggregate interface, moisture content of concrete, visco-elasticity material content.
