“…A value of 0.70 MPa was considered as the uniaxial tensile stress and was included in the modified Solid65 element command. A summary of the material properties considered within the FEA are detailed in Table 4 and are within the range of values used within previous studies [5,20,24,36,45]. The boundary conditions and rate of loading were modelled to replicate the conditions applied in physical testing, as detailed in section 2.4.1 and 2.4.2.…”

“…The utilisation of finite element analysis (FEA) to study the properties of CEBs has been very limited. Of the few studies that have utilised FEA, there has been success in modelling the mechanical behaviour of earthen construction and various approaches have been taken to do so [5,[19][20][21][22][23][24]. A previous study utilised FEA to investigate the interaction between individual interlocking CEB's stacked on top of one another, and was shown to successfully replicate the cracking pattern observed within physical testing [20].…”

“…A previous study utilised FEA to investigate the interaction between individual interlocking CEB's stacked on top of one another, and was shown to successfully replicate the cracking pattern observed within physical testing [20]. Further studies have utilised FEA to model structural elements such as walls to determine the behaviour of traditional adobe masonry and CEBs under static and seismic loading [19,24]. Generally, the application of FEA has proven successful in determining accurate load-displacement curves, crack patterns, local stresses and deformations.…”

“…In the macromodelling technique, masonry is modelled as a homogeneous material with equivalent mechanical properties (see e.g. : Rots 1991;Gambarotta and Lagomarsino 1997;Calderini and Lagomarsino 2008;Illampas et al 2014;Parisi et al 2019). This technique is more practical due to its memory efficient processing and user-friendly mesh generation (Mahini 2015).…”

All around the world, non-engineered masonry constructions (NECs) typically have high vulnerability to seismic ground motion, resulting in heavy damage and severe casualties after earthquakes. Even though a number of computational strategies have been developed for seismic analysis of unreinforced masonry structures, a few studies have focussed on NECs located in developing countries. In this paper, different modelling options for finite element analysis of non-engineered masonry buildings are investigated. The goal of the study was to identify the modelling option with the best trade-off between computational burden and accuracy of results, in view of seismic risk assessment of NECs at regional scale. Based on the experimental behaviour of a single-storey structure representative of Indian non-engineered masonry buildings, the output of seismic response analysis of refined 3D models in ANSYS was compared to that of a simplified model based on 2D, nonlinear, layered shell elements in SAP2000. The numerical-experimental comparison was carried out under incremental static lateral loading, whereas nonlinear time history analysis was performed to investigate the dynamic performance of the case-study structure. Analysis results show that the simplified model can be a computationally efficient modelling option for both nonlinear static and dynamic analyses, particularly in case of force-based approaches for design and assessment of base isolation systems aimed at the large-scale seismic vulnerability mitigation of NECs.

This paper presents the results of a numerical study using the finite element method to assess the effect of wall thickness and a moist region along the wall base on the out-of-plane lateral stability of adobe walls. The models consisted of cantilever unreinforced adobe walls with a thickness of 25 cm, 30 cm, and 40 cm. Numerical analyses were performed for four lengths (L) of the moist region and for dry walls. The moist region was modelled with material characteristics corresponding to partially saturated and nearly saturated adobe. The results showed the detrimental effect of moisture along the lower portion of the wall on the out-of-plane lateral strength. The out-of-plane lateral strength reduction ratio dropped significantly as L increased. A high slenderness ratio was found to be critical for cantilever adobe walls when L extended beyond half of the wall length. The results provided insights concerning the role of wall thickness in the stability against overturning.
