“…10(a) that toppling failure occurs in the case of the cuboid block. In addition, from this figure, a slipped region and settlement of the upper right area of the backfill were re-observed both for y ¼ 4.5 m and y¼ 8.5 m. The settlement of the backfill associated with the deformation of the masonry wall has also been reported in realscale tests with a shaking table (Yamamoto et al, 2010).…”

“…To clarify this complex mechanism, researchers have employed various approaches, such as centrifuge model experiments (Yoshida et al, 2007(Yoshida et al, , 2009, real-scale tests (Yamamoto et al, 2010), the continuum numerical model (Dewoolkar et al, 2009;Colas et al, 2010), the discontinuous numerical model (Claxton et al, 2008;Kamai and Hatzor, 2008;Yoshida et al, 2007) and the homogenization theory (Mathieu et al, 2012). Although such works have produced many results, the The Japanese Geotechnical Society www.sciencedirect.com journal homepage: www.elsevier.com/locate/sandf contribution of each individual block to the overall stability of the wall has not been well discussed due to the difficulty in taking quantitative measurements.…”

The shape effect of the blocks comprising a dry-stone masonry retaining wall under seismic loading was investigated through centrifuge model tests and numerical simulations using the three-dimensional discrete element method. Variations in block shape, namely, cubic-shaped and wedge-shaped, were compared. For both the physical experiments and the numerical simulations, seismic resistivity was higher in the wall of wedge-shaped blocks than in the wall of cuboid blocks, although the total mass was larger for the wall of cuboid blocks. Therefore, a detailed investigation was performed by the discrete element model to explore the mechanism of the shape effect. We found that the surface area, which contributes to the frictional resistance between each stone block and the backfill, is the key parameter to mobilizing the anti-seismic strength of a dry-stone masonry retaining wall.
