Design Issues of Wind Turbine Towers

Abstract

Wind turbine design has advanced significantly in terms of its size and type in recent years. However, Conventional conical steel towers are predominantly used as a main structural system for wind turbine towers. However, to transport the tower to construction site seems to be a major issue. This study investigates the use of square cross-sections for wind turbine towers for different thickness and height as an alternative to circular cross-sections. Vortex shedding is also considered in the analyses.
