“…In summary, the available candidate case studies for numerical simulation are few in number and mostly concerning stack bond prisms [7,[13][14][15][16][17][31][32][33][34][35][36][37][38][39][40][41]. Case studies of walls in running bond are not uncommon [33,40,[42][43][44] but tests on walls in Flemish bond are rare [45] while a few suitable examples of English bond pillars were also identified [13,33].…”

“…The vast majority of these cases involve the characterization of clay brick masonry with a few exceptions involving stone block masonry [14,35] or compressed cement block masonry [15]. All mortars were either cement or lime/cement mortars, with one exception where pure lime mortars were used [32]. …”

“…Abiding to the principle aims of structural micro modeling, which include the direct, rather than the phenomenological, simulation of structural behavior and failure, and in an effort to establish a generally applicable modeling approach, three-dimensional micromodeling appears to be the most promising and advantageous method.

“…In the cases where it was not reported, the Poisson's ratio for the units was chosen as being equal to 0.15 while a value between 0.15 and 0.25 was chosen depending on the type of mortar. In [32,38] a weak lime mortar was used, so a value of 0.25 was adopted. For [31,33,37,40,43], for which a cement/lime mortar was used, a value of 0.20 was adopted.…”

The paper focuses on the numerical prediction of the compressive response of masonry by means of detailed micro-modelling techniques. In such a model, the material constituents (mortar and units) and the unit-mortar interfaces are separately described by means of specific constitutive equations.The available modeling choices are evaluated through a literature review of related case studies. A systematic approach is proposed and is corroborated by the numerical simulation of a large number of experimental cases from various sources. A total of fifty experimental results are simulated resulting in an overall good prediction of the compressive strength and elastic modulus of the masonry composite, as well as a realistic depiction of the failure mode.This study focuses on the numerical prediction of the compressive strength of masonry, extending to issues pertaining to global stiffness, failure mode, hardening and softening behavior of masonry and their numerical simulation. The masonry typology considered consists of solid units, primarily brick, and mortar of mostly lower strength and higher deformability. Highlights• The behavior of masonry in compression is investigated using micro-models• A combined smeared cracking-plasticity law is used for the units and mortar• A total of fifty experimental compression tests are simulated• Compressive strength and Young's modulus of masonry is well approximated• Remarks on the behavior and failure mode of masonry in compression are made

“…The modeling method has been applied to experimental cases consisting of stack bond, running bond and Flemish bond masonry composites found after an extensive literature review on masonry in compression [23][24][25][26][27][28][29][30][31][32][33][34][35][36]. Only case studies providing experimental values for the Young's modulus of the constituents have been considered.…”

The present paper proposes a new homogenization method in order to determine the in-plane strength domain of a single-wythe, running-bond masonry wall. Two approaches, one analytical and one numerical, relying on the limit analysis/yield design framework, are introduced. The main novelty of these two approaches is that they allow to take into account a finite strength for the blocks and the mortar, as well as a non-zero thickness for the joints, without any specific assumption on the state of stress or strain of the structure. For that purpose, 3D virtual failure mechanisms are considered. A comprehensive parametric study is performed, showing that in many cases, the analytical approach is as precise as the numerical one for a much lower computational cost. Finally, the strength domains obtained by the proposed approaches are compared to the results of an extensive experimental study on reduced-scale masonry wallettes available in the literature, showing a good agreement in the compression-compression range.
