The Applied Element Method (Meguro and Tagel-Din, 2000, 2001, 2002, Tagel-Din and Rahman, 2004) is an innovative modeling method adopting the concept of discrete cracking. In the Applied Element Method (AEM), the structures are modeled as an assembly of relatively small elements, made by dividing of the structure virtually, as shown in Figure 1a–1b. The elements are connected together along their surfaces through a set of normal and shear springs. The two elements shown in Figure 1care assumed to be connected by normal and shear springs located at contact points, which are distributed on the element faces. Normal and shear springs are responsible for transfer of normal and shear stresses, respectively, from one element to the other. Springs represent stresses and deformations of a certain volume as shown in Figure 1c.

Applied Element Method (AEM) is based on dividing the structural members into elements connected through springs. Each spring entirely represents the stresses, strains, deformations, and failure of a certain portion of the structure. AEM allows to perform static and dynamic analysis (Tagel-Din & Meguro 1999; Tagel-Din & Meguro 2000; Meguro & Tagel-Din 2002). In this study, a non-linear structural analysis software “Extreme Loading for Structure (ELS)” (Applied Science International 2017) based on AEM was used.

The finite element technique is well-established: however, the known deficiencies like continuity requirement and simulating infinite boundary conditions prompted the development of a large number of techniques for displacement analysis of solid media. The discrete element method (Cundall & Strack, 1979), the particle model (Bažant, Tabbara, Kazemi, & Pijaudier-Cabot, 1990), rigid body-spring models (Kawai, 1986), lattice models (van Mier, 1997), applied element method (Meguro & Tagel-Din, 2000), peridynamics (Silling, 2000), scaled boundary finite elements (SBFE) can be listed among these techniques. The direct modelling of crack separation/contact in plain concrete structures is attractive; however, these models are numerically very costly. The finite difference method, used commonly for the modelling of embankment dams (Kartal, Çavuşli, & Geniş, 2019), has also seen new interest for modelling of gravity dams with a focus on bearing failure on foundation (Li, Wu, & Zhang, 2022) and fault distance effects (Karalar & Cavusli, 2020). The computational load for dense models is significant (Chopra, 2020), requiring massive computing efforts to this end (Li et al., 2022).
