The paper presents a monitoring system applied to an existing steel tubular wind tower located in Italy,having almost 45 meters of total height. The monitoring sys-tem was comprisedby strain-gaugesandthermal couples,mounted on the tower shell at 21 meters of height, and few accelerometers, located along the tower’s height. The monitor system was used for two main reasons: i) to understand the nature of the resonance problem experienced by the tower and ii) to evaluatetheeffective stresses distribution on the shell with different rotor velocities. Finally, adebate about the extension of the life of the wind tower is proposed.

Abstract
The paper presents a monitoring system applied to an existing steel tubular wind tower located in Italy,having almost 45 meters of total height. The monitoring sys-tem was comprisedby strain-gaugesandthermal couples,mounted on the tower shell at 21 meters of height, and few accelerometers, located along the tower’s height. The monitor system was used for two main reasons: i) to understand the nature of the resonance problem experienced by the tower and ii) to evaluatetheeffective stresses distribution on the shell with different rotor velocities. Finally, adebate about the extension of the life of the wind tower is proposed.File | Dimensione | Formato | |
