Monitoring of transmission towers

A monitoring system, applied to the specific conditions of slender towers is presented in principle for the Telecommunication Tower of Cottbus (TTC). The concept is based bn simultaneous measurement of the wind situation and the vibration behaviour at discrete points of the structure. Using modal analysis a method has been developed, which allows conclusions from the known dynamic responses at those discrete points to govering quantities of serviceability such as inclinations and stresses of the overall structure. In addition, the measurement data is used for a realistic derivation of the correlation between wind effects and dynamic responses of the tower applying neural networks.
