Comparison of wind turbine tower failure modes under seismic and wind loads [PDF]

, 2019
This paper studies the structural responses and failure modes of a 1.5-MW horizontal-axis wind turbine under strong ground motions and wind loading. Ground motions were selected and scaled to match the two design response spectra given by the seismic ...
