Efficiency of Transmitting Boundaries on Dynamic Response of Soil- Structure Interaction Systems

Abstract

In this study, efficiency of transmitting boundaries which is one of the local procedures is investigated for dynamic analysis of the soil-structure interaction systems and the results are compared with traditional boundaries. Sarıyar concrete gravity dam is chosen for an application. For the soil-structure interaction system of the chosen dam, two different finite element models are prepared. In the first model, the infinite soil media on which the dam has been built is classically represented with finite size using traditional boundaries. In the second model, the infinite soil region is represented with finite size using transmitting boundaries. Dynamic analysis of these soil-structure interaction systems are performed with a computer program for approximate 3-D analysis of soil-structure interaction problems (FLUSH). As a result of the analyses, spectrums of acceleration, velocity and displacement are obtained for crest point of the dam.
