Dynamic Soil-Structure-Interaction Transmitting Boundary for Transient Analysis
The aim of this thesis is to investigate and develop alternative methods of analyzing problems in dynamic soil-structure-interaction. The main focus is the major difficulty posed by such an analysis-the phenomenon of waves which radiate outward from the excited structures towards infinity. In numerical calculations, only a finite region of the foundation medium is analyzed and something is done to prevent the outgoing radiating waves to reflect from the region's boundary. The present work concerns itself with the study of such effects, using the finite element method, and artificial transmitting boundary at the edges of the computational mesh. To start with, an investigation of the main effects of the interaction phenomena is carried out employing a widely used model, considering dynamic stiffness of the unbounded soil as frequency independent.
