In this paper, using finite element method, a FEM model of wind turbine towers with the consideration of soil-structure interaction using spring-damping element was proposed to investigate their dynamic response to multi-dimension seismic excitation in time domain. The updated Lagrange FEM formalism has been adapted to discrete the equation and use Newmark integral method to solve it step by step...
Based on considering the fluid-solid coupling problem in geotechnical engineering, the dynamic FEM model of fluid-solid interaction was established by use of Finite Element Method. Through application the established model to practical project, the results indicate that seismic response of the slope increases with the rise of water level, and so the fluid-solid interaction was of great influences...
