Rigid block models for masonry structures

“…The fact that rigid block deformation seems to be the preferred failure mode for real masonry structures stems from mechanical characteristics, such as toughness, interlocking, finite friction and cohesion, that are not inherent to the simplified NRNT continuum model. There exists an extensive literature on discrete element approximation of real masonry structures (see e.g., Forgács et al, 2017 or the recent book (Sarhosis et al, 2016) may be consulted for reference) and many studies proposing macro-block analyses (see for example Angelillo et al (2014) and references therein).…”

Evaluation of different approaches for the estimation of the seismic vulnerability of masonry towers

“…This has similarities with the behaviour of low bond strength masonry which often encountered in masonry towers (Sarhosis et al 2016a). Typical examples of masonry structures that have been modelled using the discrete element method and UDEC software include masonry arches Forgacs et al 2017); wall panels (Sarhosis et al 2015;Sarhosis & Sheng 2014;Bui et al 2017); and ancient colonnades (Sarhosis et al 2016b;Pulatsu et al 2017).…”

Numerical Analysis of an FRP-Strengthened Masonry Arch Bridge

“…With this need in mind, in recent years, different calculation methods and guidelines (e.g., UIC guideline) 1 for the evaluation of the ultimate (ULS) and serviceability limit states (SLS) of masonry bridges have been developed. Among the available methods for the structural analysis of masonry bridges, it is possible to find: simplified methods (Zhang et al, 2018), numerical method for assess the seismic capacity (Pelà et al, 2013;Zampieri et al, 2014Zampieri et al, , 2015aSarhosis et al, 2016;Mahmoudi Moazam et al, 2018;Marefat et al, 2019), methods based on the limit analysis (Basilio et al, 2014;Chiozzi et al, 2017;Bertolesi et al, 2018), analysis strategies able to take into account the settlement of the supports (Galassi et al, 2018a,b;Zampieri et al, 2018aZampieri et al, ,b, 2019 or geometry uncertainties (Cavalagli et al, 2017), macro-element models (Cannizzaro et al, 2018;D'Altri et al, 2019), and methods based on finite element modeling (FEM) (Brencich and Sabia, 2008;Costa et al, 2016;Scozzese et al, 2019), discrete element modeling (DEM) (Sarhosis et al, 2016(Sarhosis et al, , 2019Forgács et al, 2017Forgács et al, , 2018Stockdale et al, 2019) or a combination of both (Milani and Lourenço, 2012).…”
