Development of 3-D Dynamic Infinite Elements for 3D Soil-Structure Interaction Analysis in Multi-layered Halfspaces
초록
In this paper, three dimensional dynamic infinite elements are developed for the soil-structure interaction analysis in multi-layered halfspace. For the efficient discretization of 3-D for field regions, five types of dynamic infinite elements are developed. They are the horizontal, vertical, upper horizontal conner, lower vertical conner and conner of conner infinite elements. The shape functions of the infinite elements are based on the approximate expressions of the analytical solutions of the propagating waves in the infinite region. Numerical example analyses are presented for demonstrating the effectiveness of the proposed infinite elements.
