TL;DR: A review of methods applicable to the study of masonry historical construction, encompassing both classical and advanced ones, is presented in this paper, where 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.

TL;DR: In this article, the seismic performance of existing masonry arch bridges is evaluated by using nonlinear static analysis, as suggested by several modern standards such as UNI ENV 1998-1 2003, OPCM 3274 2004, and FEMA 440 2005.

TL;DR: In this article, a numerical model for nonlinear analysis of masonry structural elements based on Continuum Damage Mechanics is presented, where the material is described at the macro-level, i.e. it is modeled as a homogeneous orthotropic continuum.

TL;DR: In this paper, two stress transformation tensors, related to tensile and compressive stress states, respectively, are used to establish a one-to-one mapping relationship between the orthotropic behavior and an auxiliary model.

TL;DR: In this article, a procedure to simulate the growth and propagation of localized tensile cracks on quasi-brittle materials is presented, where the so-called smeared damage approach is recovered and improved in order to represent crack localization and avoid spurious mesh-bias dependence in the discrete problem.
