摘要：
The steel-concrete hybrid wind turbine tower is characterized by the lower part of the traditional steel tube tower replaced with the concrete segment. Because of the mass and stiffness mutation along the height of the tower, its seismic response is significantly different from that of the traditional single-tube steel wind turbine tower. Two detailed finite element models for a single-tube steel tower and a steel-concrete hybrid tower for 2.0 MW wind turbines built in the same wind farm, are developed with ABAQUS. The mode-superposition response spectrum method is applied to calculate and compare the seismic responses of these two towers under three different site conditions. Three groups of ground motions corresponding to three site conditions are used to analyze the dynamic response of the steel-concrete hybrid tower by nonlinear time series analyses. The numerical results show that the mode-superposition response spectrum method is not safe to calculate the seismic response of the steel-concrete hybrid tower directly and the time series analysis should be a necessary supplement in engineering design. The internal force and horizontal displacement responses at the top of the hybrid tower reach their maximums under the medium hard soil site and the soft soil site respectively. The first three modes have obvious contributions on the dynamic response of the steel-concrete hybrid tower. The dynamic response corresponding to the second mode response is the largest contribution, which shows the contributions of higher modes are significant. © 2022, Solar Energy Periodical Office Co., Ltd.
