| Abstract: | 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. |
| |
| Keywords: | vibration and wave concrete Vibration reduction damping ratio free vibration method |
