| Popis: | The paper focuses on simulation of dynamic “structure – soil” interaction and unbounded soil halfspace.Principles for new finite elements developed in LIRA-SAPR software are described. These finite elementssimulate the interaction between bounded domain of soil and the rest part of the half-space. The scaled boundary finite-element method governs these elements. To verify the elements, two problems are solved. The first problem considers the bounded soil where the developed boundary finite elements are introduced. The second problem considers the soil of a relatively large size. Boundary conditions do not influence the wave propagation (conditionally may be treated as unbounded half-space) due to dimensions of soil size. Results differ by 3-8%. |
