This paper presents an ongoing full scale monitoring campaign carried out over a light tower, measuring simultaneous wind induced loading and response. Wind field is supplied by an ultrasonic anemometer installed on the top of the pole. The dynamic response of the structure is recorded by MEMS accelerometers and strain gauges. In parallel, a 3D model of the top and two sectional models of the shaft are investigated in the wind tunnel, with the aim of evaluating the aerodynamic properties of the pole. The analysis of acquired data will be used for the calibration of models of the response to stationary and non-stationary wind events.

Abstract
This paper presents an ongoing full scale monitoring campaign carried out over a light tower, measuring simultaneous wind induced loading and response. Wind field is supplied by an ultrasonic anemometer installed on the top of the pole. The dynamic response of the structure is recorded by MEMS accelerometers and strain gauges. In parallel, a 3D model of the top and two sectional models of the shaft are investigated in the wind tunnel, with the aim of evaluating the aerodynamic properties of the pole. The analysis of acquired data will be used for the calibration of models of the response to stationary and non-stationary wind events.
