Many countries have been promoting their national projects to examine the construction of the wind-turbine power-generating stations in the ocean. In general, the structure of an aerogenerator is heavy at the top due to the higher position of the center of gravity as a heavy nacelle is set at the top of the aerogenerator tower. Because the dynamic response of an aerogenerator increases greatly due to the top position of the heavy weight, reductions in the responses and improvements of the seismic and wind resistance levels are necessary. This study examined a response control system which is designed to reduce the structural responses and to upgrade the resistance performances against earthquakes and wind excitation. In this paper, a design method and loading tests of elasto-plastic dampers are introduced to investigate the mechanical characteristics of them. In order to confirm the structural seismic and wind response control effects by the damping devices, preliminary analyses and a set of vibration tests using a 1/16-scale model of an aerogenerator were conducted. The results obtained from analyses and tests are reviewed.
