Bridge-Tendons Vibration

To minimize the problem associated with the vibration of tendons, it is preferable to ensure the natural frequency of tendon is nowhere close to that of the deck or traffic.

However, it is often suitable to set the free length of tendon to the maximum of 12m.

The vibration frequency of highway traffic may be taken between the range of 1Hz to 3Hz. For rail traffic the frequency is dependent of the speed and axle spacing.
