“…However, they also showed the magnitude of amplification was influence by magnitude of damping ratio used in numerical modeling. The selection of Rayleigh damping coefficients for the soil was investigated by Ling et al [30] who determined that for models with a peak acceleration of 0.4 g, a 15 % and for models with maximum acceleration of 0.8 g, a 5 % damping value produced the most satisfactory results.…”

Abstract. Most of the proposed methods for obtaining the free vibration natural frequency of the retaining wall assume the behavior of the wall in the two-dimensional domain, and they are not able to express the three-dimensional behavior of these structures in a satisfying manner. Moreover, the effect of damping has not yet been considered in analytical study. In this paper, the plate theory and Galerkin method is employed to analyze the free vibration of a wall-reinforcement-soil system in the three dimensional domain and survey the effect of damping on the natural frequency of a retaining wall. So, the retaining wall is modeled as a clamped-free plate and the stiffness of the soil and reinforcements existing behind the wall are modeled as a set of springs and the damping effect of the system is modeled by a set of dampers located at the back of the Retaining wall and attached to it. The results of the proposed model are compared with both the results of the other researchers and the ones from finite element method (FEM). They are also compared with the results of a full-scale experiment and it shows a good agreement. The proposed method which uses the plate theory, also yields the free vibration natural frequencies of the wall's extensional modes with an acceptable accuracy. Finally, the effect of tensile and compressive behaviors of the soil and the reinforcements on the fundamental frequency of a reinforced retaining wall is studied.Keywords: reinforced retaining wall, reinforcement, 3D vibration, analytical method, damping ratio, mode shape.

“…The selection of Rayleigh damping coefficients for the soil was later investigated by [27], concluding that for models with a peak acceleration of 0.4 g, a 15% damping value produced the most satisfactory results. For models with maximum acceleration of 0.8 g, the damping was lowered to 5%.…”

“…The seismic behaviour of GRS retaining walls has been numerically investigated using mainly FLAC or FLAC3D codes [21,22,26,29,30], DIANA-Swandyne-II [24,25,27], DYNA3D or LS-DYNA [23,28] and ABACUS [14]. Different elements were assumed to model the reinforcement layers (cable elements, shell elements, bar elements, truss elements and beam elements), assuming in general elastic or elastic-plastic behaviour.…”
