Seismic Response Analysis of Wind Turbine Tower with Soil-Structure Interaction

CAO Qing,ZHANG Hao(College of Water Conservancy and Hydropower Engineering,Hohai University,Nanjing 210098,China)  
Using finite element method,a FEM model of wind turbine tower considering soil-structure interaction simulated by the spring-damping element is proposed to investigate its dynamic response under multi-dimension seismic excitation in time domain.The updated Lagrange FEM formalism is adapted to discrete the equation and to use Newmark integral method to solve it step by step.Through this numeral analysis on the influence of P-Δ effect,the effects of soil-structure interaction and vertical seismic action on structure's dynamic property,the time-history response rule for the tower is studied with a real example.The result show that the effect of the soil-structure interaction on the seismic response of wind turbine tower structure is significate and should not be ignored.In line elastic range,the influence of vertical seismic loads and the P-Δ effect are not notable.
