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.

“…Following the pioneering works by Okabe (1926) and Mononobe & Matsuo (1929), several studies have tackled the problem of computing dynamic earth pressures on retaining structures with a theoretical (Steedman & Zeng, 1990;Lancellotta, 2007;Mylonakis et al, 2007;Kim et al, 2010), experimental (Atik & Sitar, 2010) or numerical approach (Gazetas et al, 2004;Evangelista et al, 2010). In the last decade, following the seminal works by Newmark (1965) and Richards & Elms (1979), more and more works have been devoted to the computation of wall displacements, in the light of a performance-based design (Ling, 2001;Huang et al, 2009;Basha & Babu, 2010).…”

1Some remarks on the seismic behaviour of embedded cantilevered retaining walls R. CO NTI Ã , G . M. B. V IGGIANI † and F. B URALI D 'AREZZO ‡ This paper is a numerical investigation of the physical phenomena that control the dynamic behaviour of embedded cantilevered retaining walls. Recent experimental observations obtained from centrifuge tests have shown that embedded cantilevered retaining walls experience permanent displacements even before the acceleration reaches its critical value, corresponding to full mobilisation of the soil strength. The motivation for this work stems from the need to incorporate these observations in simplified design procedures. A parametric study was carried out on a pair of embedded cantilevered walls in dry sand, subjected to real earthquakes scaled at different values of the maximum acceleration. The results of these analyses indicate that, for the geotechnical design of the wall, the equivalent acceleration to be used in pseudo-static calculations can be related to the maximum displacement that the structure can sustain, and can be larger than the maximum acceleration expected at the site. For the structural design of the wall, it is suggested that the maximum bending moments of the wall can be computed using a realistic distribution of contact stress and a conservative value of the pseudostatic acceleration, taking into account two-dimensional amplification effects near the walls.

“…Numerical analysis of embedded cantilever retaining walls in dry coarse-grained soil under seismic condition using Tolmezzo time acceleration history data has been analyzed in FLAC [8]. A number of studies has been done on other types of retaining walls such as gravity, cantilevered, anchored walls or mechanically stabilized earth retaining walls under seismic condition ( [9], [10], [11], [12], [13], [14]). …”
