Vibration Measurements and Damping Evaluation of Cable​s

Cable forces and cable damping values are very important both during and after construction as well as for monitoring.

DYWIDAG offers vibration measurement for tension members to quickly and efficiently determine both cable forces and damping values.

A 3-dimensional accelerometer, placed on the cable, registers its movements. Each cable has an individual vibration characteristic depending on cable force, dimensions, the type of anchorage and on possible cable supports.

Eigenfrequencies and eigenmodes correspond to the vibration characteristics and can be calculated from the vibration measurement. The obtained cable eigenfrequencies are used to calculate tensioning forces.

Damping values can be calculated by determining the decay of vibration amplitudes.

Measurement of one cable only takes only a few minutes
