Analysis of Prestressed Concrete Tower for Wind Turbine Generator

Abstract:

In the paper is presented a parametric study on possibilities of designing and realizing a prestressed reinforced concrete tower for a wind turbine, WEG 400, as an alternative solution replacing a steel structure. WEG 400 is a generation of a double-blade wind turbine with the rotor diameter of 36.7 m. Key design criteria include extreme static/dynamic loads, cyclical loading and natural frequency. The supporting structure of the tower needs to be easy to dispose from prefabricated prestressed concrete elements.
