“…The failure envelope used in this study was the Mohr-Coulomb criterion with a tension cut-off. This model existed in the discrete element code; its relevance was checked in the case of masonry walls [20]. The Mohr-Coulomb criterion is expressed in terms of the principal stresses σ 1 , σ 2 , and σ 3 , which constitute the three components of the generalized stress vector for this model (n = 3), whereby the three principal stresses are: σ 1 ≤ σ 2 ≤ σ 3 .…”

Rammed earth is attracting renewed interest throughout the world thanks to its "green" characteristics in the context of sustainable development. Several research studies have thus recently been carried out to investigate this material. Some of them attempted to simulate the rammed earth's mechanical behavior by using analytical or numerical models. Most of these studies assumed that there was a perfect cohesion at the interface between earthen layers. This hypothesis proved to be acceptable for the case of vertical loading, but it could be questionable for horizontal loading. To address this problem, discrete element modeling seems to be relevant to simulate a rammed earth wall. To our knowledge, no research has been conducted thus far using discrete element modeling to study a rammed earth wall. This paper presents an assessment of the discrete element modeling's robustness for rammed earth walls. Firstly, a brief description of the discrete element modeling is presented. Then, thirteen parameters that were necessary for discrete element modeling were identified. The relevance of the model and the material parameters were assessed by comparing them with experimental results from the literature. The results showed that, in the case of vertical loading, interfaces did not have an important effect. In the case of diagonal loading, model with interfaces produced better results. Interface's characteristics can vary from 85% to 100% of the corresponding earthen layer's characteristics.

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.

“…A brick masonry wall was analyzed in static and dynamic loadings and found capable to predict appropriate response. Using similar approaches, Lourenco et al [7] and Senthivel et al [8] investigated on dry joint cut sawn stone masonry walls to verify the experimental investigations. This concept has also been applied to investigate the effectiveness of wooden bond beams in dry stone masonry houses [9].…”

Brick masonry constructions are very common in many areas in the world and their failure in earthquakes has been the cause of many deaths. Since human safety is main issue of disaster management, people are more concerned about the structural assessment and strengthening of those constructions. One historical brick masonry house located in Kathmandu world heritage site is modeled by FEM (finite element method) and analyzed in El Centro earthquake ground motions. Bricks are modeled as solid elements and the interfaces between the brick units are modeled as zero thickness joint elements. Then, non-linear analyses of the house are applied satisfying the famous Mohr-Coulomb failure criterion. The result shows that the house is very weak and sustains large deformation in El Centro 1940 Earthquake. A strengthening solution modifying the connections of existing elements and adding wooden frame inside the house can reduce the deformations significantly.
