| Abstract: | Dynamical characters of the cable-stayed bridge with single tower are considered by the experimental method. Natural frequencies of the bridge are obtained by the shock, wind excitation and hammering method and these experimental techniques are compared. Damping ratios and vibration model of the system are analyzed by the transfer function method. The vibration character of the bridge is evaluated. |

| Keywords: | cable-stayed bridge natural frequency damping ratio vibration model |
