Abstract
Horizontal Axis Wind Turbines (HAWT) may experience catastrophic failures due to very strong wind and/or seismic loads. Such loads, if not properly addressed, may result in excessive deformations which, in turn, may cause significant damage, or even collapse of wind turbines. This research proposes the development of a novel nonlinear dynamic response of wind turbine towers, in order to produce more reliable designs, especially in the case of ultimate loading of horizontal axis wind turbines. The approach is highly nonlinear, and requires advanced numerical techniques to achieve accurate solutions. The programming of these techniques is achieved using the Embarcadero's Delphi, which is a Windows based Object Pascal programming environment.
