| Abstract: | It is very complex for us about damped theory in the wood structure. In this paper, vibration theory and measure skill to be used, amplitude frequency of frequency response function in the wood samples have been determined with resonance method, and damping parameter of wood samples in the forced vibration have been determined with half-power points. |

| Keywords: | Damping Amplitude frequency Half-power points Forced vibration |
