To investigate the seismic performance of various wind turbine structures under different types of ground mo-tions,this paper utilized the ABAQUS software to establish three-dimensional finite element models of a conventional 5 MW wind turbine structure and steel-concrete hybrid wind turbines.Nonlinear time history analysis is conducted to in-vestigate and compare their dynamic responses under four types of ground motion recorded in the same earthquake,namely a near-field pulse-like ground motion with the forward-directivity effect,a near-field pulse-like ground motion with the fling-step effect,a near-field non-pulse ground motion,and a far-field ground motion.The results indicate that the ground motion types significantly impact the structural response of wind turbine structures.Furthermore,under the same ground motion,different wind turbine structures exhibit significant variations in seismic response.
