“…An example of the former approach is the work of Lourenço [70] and Lourenço et al [75] which proposed a non-linear constitutive model for in-plane loaded walls based on the plasticity theory, for which the material admissible field is bounded by a Hill-type yield criterion for compression and a Rankine-type yield criterion for tension (Fig. 21).…”

A review of methods applicable to the study of masonry historical construction, encompassing both classical and advanced ones, is presented. Firstly, the paper offers a discussion on the main challenges posed by historical structures and the desirable conditions that approaches oriented to the modeling and analysis of this type of structures should accomplish. Secondly, the main available methods which are actually used for study masonry historical structures are referred to and discussed.The main available strategies, including limit analysis, simplified methods, FEM macro-or micro-modeling and discrete element methods (DEM) are considered with regard to their realism, computer efficiency, data availability and real applicability to large structures. A set of final considerations are offered on the real possibility of carrying out realistic analysis of complex historic masonry structures. In spite of the modern developments, the study of historical buildings is still facing significant difficulties linked to computational effort, possibility of input data acquisition and limited realism of methods.

“…In particular, the shear failure of masonry walls has been modelled by means of simplified micro-modelling using interface elements to model existing and arising planes of weakness, Lourenço & Rots [1]. Macro-models have also been employed for this purpose, taking into account the orthotropic properties of masonry, Lourenço et al [2], Syrmakezis & Asteris [3] and Pelà et al [4]. Instead, more limited attention has been allocated to the detailed simulation of the masonry response and failure in compression.…”

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

“…Adreaus [13], para poder modelizar ciertas características de la fábrica (su comportamiento), que se hacen difíciles de analizar por técnicas estándar de la Mecánica de Medios Continuos y el Método de los Elementos Finitos uni y bidireccionales, discretiza el sólido fábrica en un número finito de celdas elementales compuestas por elementos barra a manera de una celosía, que poseen leyes constitutivas multilineales. Lourenqo et al [14] han propuesto un macromodelo continuo anisótropo. Molins y Roca [ 151 han desarrollado un modelo para el análisis no lineal por la geometría y el material de estructuras de fábrica formadas por elementos lineales de geometría curva y variable basada en la Formulación Matricial Generalizada.…”
