2D modelling of a dry joint masonry wall retaining a pulverulent backfill

Abstract

International audienceThis work focuses on an analysis of dry joint retaining structures based on yield design theory: the stability of the masonry is assessed using rigid block and shear failure mechanisms in the wall and its backfill. An application of this simulation on 2D scale-down brick and wood models is then addressed, showing close agreement between theoretical predictions and experimental results. Further development on this work, including application of this theory on dry-stone retaining walls, is discussed as a conclusion

Yield design modelling of dry joint retaining structures

“…They indeed show that yield design succeeds in predicting experimental results with an error rate around 10%. Further details can be found in Colas et al [21]. Figure 6 presents theoretical ultimate heights depending on experimental results.…”

“…Colas et al [21]. In this experiment, models are built with vertical faces and leaning joints (from −12 to 6 • ), and then loaded with a horizontal backfill until failure.…”

The effects of block shape on the seismic behavior of dry-stone masonry retaining walls: A numerical investigation by discrete element modeling

“…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.…”

2D-DEM modelling of the formwork removal of a rubble stone masonry bridge

“…In the literature and considering the nature of the system, there are mainly four methods that can be found. The first one is the rigid block limit analysis [1][2][3], which is suitable when the study focuses on the ultimate loading of a system at failure. There is no access to the deformation field.…”
