“…The reaction of base-isolated structures differs with superstructure time intervals, base elasticity and breach dimensions among base and neighboring support. Tufan Cakir 5 [2014] Studied on the impacts of backfill and subsoil contact on cantilever wall seismic performance. To study the seismic comeback of the cantilever wall, a 3-dimensional finite element design with a viscous edge is developed.…”

From the past studies, every engineering structure was designed to withstand all external and internal forces applicable to the structure. For this many design methods are implemented and different techniques are found manually, experimentally and practically. One of the parameters which influence the analysis results is, support condition of the structure. Assuming fixed or pinned support in regular analysis of structure considering soil interaction with foundation may not produce accurate results as support condition differ by type of soil ie., loose, medium or hard & their characteristics. So, there is need to study about structural interaction with soil and their outcome deeply. Now a day’s soil structure interaction studies are playing major role in the analysis & design of structures. Many studies are carried out on structure interaction of soil considering seismic or lateral forces. This paper reviews the studies carried out on structural interaction with soil and its impacts on various reinforced concrete buildings subjected to dynamic loads

In this study, a coupled model based on the boundary element and the finite element methods is used to analyze the dynamic responses of two-dimensional model resting on layered soil medium under spatially varying ground motion effects. The dynamic response of the soil-structure systems is obtained in the frequency domain. The results of the finite element and the coupling finite-boundary element models are compared with each local soil conditions. In the seismic analysis of the system, the substructure method is employed. In the standard finite element model, both the structure and semi-infinitive soil medium are modeled by the finite elements, however, in the coupling finite-boundary element model, the structure and the soil medium are modeled respectively by the finite and boundary elements, both. In the last method, the special features and advantages of two methodologies are considered. In the coupling of finite-boundary element method, the equivalent finite element approach is used in which the boundary element region is transformed as an equivalent finite element and the final system is solved as a stiffness problem. Results of the study show that the coupling finite-boundary element method can provide realistic and effective modeling of soil-structure interaction problems as compared with standard finite element method results.

Knowledge of the seismic behavior of cantilever retaining walls is an important component for their successful design in earthquake prone areas. In this study, a finite element procedure was used to investigate the effects of backfill soil properties variation on seismic response of a cantilever retaining wall. In this procedure, not only soil-structure interaction but also backfill-wall interaction was taken into consideration. Considering four different backfill soil conditions, the dynamic analyses of backfill-cantilever wall-soil/foundation system were carried out in time domain through ANSYS program. The magnitudes of lateral displacements and stresses were determined by performing non-linear time history analyses. As a result, based on the response amplification/reduction pattern observed on the lateral displacements and stresses, it is concluded that the dynamic behavior of cantilever walls is highly sensitive to the backfill characteristics.Keywords: Soil-structure interaction, Seismic response, Finite element method, Time history Konsol Bir İstinat Duvarının Sismik Davranışı Üzerinde Dolgu Etkileşiminin Değerlendirilmesi Üzerine Parametrik Bir Çalışma ÖzKonsol duvarların sismik davranışının bilinmesi, bu yapıların deprem bölgelerindeki başarılı tasarımını tesis etmek için önemli bir unsurdur. Bu çalışmada, konsol bir istinat duvarının sismik tepkisi üzerinde dolgu özellikleri değişiminin etkilerini incelemek için bir sonlu elemanlar yöntemi kullanılmıştır. Bu yöntemde zemin-yapı ve dolgu-duvar etkileşimleri dikkate alınmıştır. Dört farklı dolgu zemini koşulu dikkate alınarak, dolgu-konsol duvar-temel/zemin sisteminin dinamik analizleri zaman ortamında ANSYS programıyla gerçekleştirilmiştir. Yerdeğiştirme ve gerilmeler doğrusal olmayan analizlerle belirlenmiş ve dinamik davranışın dolgu özelliklerine oldukça duyarlı olduğu ortaya konmuştur.
