Local transmitting boundaries for transient elastic analysis

摘要

The aim of this paper is to investigate and develop alternative methods of analyzing problems in dynamic soil-structure-interaction (SSI). The interaction means that the amplitude of structural response is effected by additional energy dissipation through radiation and material Damping in the soil. The surrounding soft soil behaves as a natural damper for a massive and stiff structure supported or embedded in it. The Main focus is the major difficulty posed by such an analysis-the phenomena of waves that 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 radiation waves from reflecting at the boundary region.
