In the present paper the behavior of an elastically mounted cylinder in low and high mass-damping ratio is investigated. For high mass-damping ratio, a classical wake oscillator model is used. At the first, by neglecting all damping and nonlinear...

are in good agreement with those

calculated by microtremor technique. Irregularities in surface and subsurface geomorphic conditions tend

to have differences in results obtained by both mentioned methods. Damping ratios were derived from...

are generated. Thereupon, damping ratios -z- for different types of connections are reported. The study can be useful to help in designing of wind turbine towers with a higher level of accuracy and safety....
