It means that, as long as the dry stone walls are constructed following the state of the art of dry stone construction, the shape of the blocks does not seem to play a significant role on the wall stability.…”

“…Further experiments on slope DSRWs were carried out much more recently when Villemus et al (2006) and Colas et al (2010Colas et al ( , 2013a aimed at finding the critical height of a backfill that triggers the collapse of a DSRW. They developed analytical methods (Villemus et al, 2006;Colas et al, 2008Colas et al, , 2013b to create charts included in design guides for the French dry stone masons (CAPEB et al, 2008;ENTPE et al, 2017).

In this paper, an experimental study aiming at understanding the seismic behaviour of dry stone retaining walls is presented. Harmonic shaking table tests have been carried out on scaled-down dry-joint retaining walls involving parallelepiped bricks. It is found that a thicker wall is more resistant and that a given retaining wall is less sensitive to higher frequencies. For those higher frequencies, the walls accept larger displacements before collapsing. The displacements start to occur from a given threshold, which depends on the wall geometry but not on the frequency of the base motion. The typical toppling failure is observed for slender wall and/or low frequency inputs. For less slender walls or higher frequency inputs, walls experience local sliding failures until the complete collapse of the system. The acceleration at failure reported during the dynamic tests have been compared to the corresponding pseudo-static resistance, enabling a conservative estimate of the seismic behaviour coefficient for pseudo-static analysis of this class of retaining walls. This novel experimental dataset is aimed to serve as a validating framework for future numerical or analytical tools in the field.

“…Alternative numerical analysis procedures can be employed to investigate the behaviour of these structures. Specifically, discrete element modelling (Colas et al 2013) may be suitable for this study because it would allow to consider the structure as a series of independent elements, hypothesis closer to the real behaviour of these structures. In this case, more refined data regard to the mechanical properties of masonry are needed.…”

Enhancing the Structural Performance of Masonry Structures by Post-Tensioning

et al. 2018

Despite the evident advantages of combining masonry with prestress, their joint use has been poorly exploited during the last decades. This paper claims the high potential of masonry as a primary load-bearing material when combined with post-tensioning. This work deals with arch footbridges and antifunicular structures. With respect to the first, this research illustrates the introduction of external loads by internal post-tensioning to favourably increase the axial forces in a masonry arch, and consequently improving its structural behaviour. With respect to the second, this work shows how bending moments in a non-funicular 2D curved geometry can be eliminated through an external post-tensioning system. In summary, this research strongly expands the range of post-tensioned masonry structures that exhibit a bending-free (or quasi bending-free) behaviour and, de facto, opens up new possibilities for designs that combine structural efficient solutions with traditional materials.
