mesh. Also, the mesh does not cover lower parts of the walls, and hence any
requirement to strengthen the foundation of these buildings in order to transfer
properly the forces from the mesh to the ground will be eliminated. The reason
behind not extending the mesh to the base of the walls was based on the signif-
icant mass of adobe wall which ensures huge shear capacity, especially at the
lower parts of these walls. As a result, the main target of using mesh with the
