“…This method was first devoted to soil mechanics, but expanding on this work, it has been proved that yield design could be applied to masonry [16,17,18]. The following section describes the procedure to model a dry joint retaining wall using this method.…”

This study presents an analysis of dry masonry retaining structures based on yield design theory : the structure stability 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. Finally, the possibility of widespreading the study to periodic dry joint and dry-stone retaining structures is discussed.

“…The wall macroscopic yield criterion is calculated by a homogenization method for periodic media developed on by de Buhan and de Felice [16]. The joints will be assumed to have a purely frictional Mohr-Coulomb criterion, only depending on the block friction angle φ m , and the stones will be considered as infinitely resistant.…”

“…Vertical forces depend on the specific weight of the panel and horizontal forces are denoted by the multiplier λ that is gradually increased. An upper-bound estimate of the ultimate value of λ, corresponding to the collapse of the panel, is obtained by applying a yield design kinematic approach to the homogenized structure [12]. Following the procedure adopted by Cecchi and Vanin [13], at the collapse, when joints exhibit only frictional strength properties, the free mechanism condition is estimated through the collapse multiplier λ, that is a function of m = 2a/b,  and r = H/b.…”

Conceived as a potential alternative to the methods usually employed for evaluating the stability of jointed rock masses, the homogenization approach developed in this paper stems from the intuitive idea that, from a macroscopic point of view, a rock mass intersected by a regular network of joint surfaces may be perceived as a homogeneous continuum. The failure criterion of such an equivalent medium is theoretically determined from the knowledge of the failure conditions of the individual constituents, namely the intact rock matrix and joint interfaces. Owing to the existence of privileged material directions associated with the joint orientation distribution, this criterion turns out to be of the anisotropic frictional type, as shown by the closed‐form expression obtained in the particular case of two mutually orthogonal joint sets. This criterion is then applied to the investigation of two illustrative engineering problems: the calculation of the load‐bearing capacity of a shallow foundation on a jointed rock half‐space and the stability analysis of an excavation. Both problems are handled by means of the kinematic method of yield design, making use of the previously determined macroscopic failure condition. The upper bound estimates thus derived appear to be significantly better than those obtained from a direct analysis in which the intact rock matrix and joints are considered separately. In spite of some limitations regarding its range of applicability, which are underlined throughout the paper, the homogenization approach may constitute an appropriate general framework for the design of densely jointed rock structures. © 1998 John Wiley & Sons, Ltd.
