In a previous paper authors studied the aeroelastic behavior of complex lighting poles and antennas masts by carrying out static sectional model tests, determining aerodynamic coefficients and using them in the framework of quasi-steady theory. This paper continues the above research by illustrating the results of aeroelastic sectional model tests aimed at verifying the precision and reliability of the previous approach. The aeroelastic experiments are conducted by increasing and decreasing the mean wind velocity in order to check the presence of hysteresis phenomena.

Abstract
In a previous paper authors studied the aeroelastic behavior of complex lighting poles and antennas masts by carrying out static sectional model tests, determining aerodynamic coefficients and using them in the framework of quasi-steady theory. This paper continues the above research by illustrating the results of aeroelastic sectional model tests aimed at verifying the precision and reliability of the previous approach. The aeroelastic experiments are conducted by increasing and decreasing the mean wind velocity in order to check the presence of hysteresis phenomena.
