ABSTRACT
With the advancement of technology in composite materials, applications of laminated composites to pole structures are advantageous because of their light weight, high specific stiffnesses and high specific strengths. However, laminated poles with a long length may result in a significant change of the dynamic characteristics during various external loading. Therefore, it is essential to study the effect of fiber angles and geometries simultaneously on the frequency of layered poles. The composite pole-type structures can be practically applied to wind turbine towers. Polyzois et al. (2009) studied static and dynamic characteristics of multi-cell jointed glass fiber-reinforced polymer (GFRP) wind turbine towers.
