The renaissance bell tower of San Benedetto in Ferrara (Italy) has been investigated to understand its nonlinear dynamics correctly with the Non-Smooth Contact Dynamic (NSCD) method. masonry structure modelled Discrete Element Methods (DEM), assuming rigid blocks and frictional joints, aim recreate actual configuration inclination a fictitious perfect vertical shape order assess influence initial slope on dynamics. contacts between are governed by Signorini's impenetrability condition...
Advanced numerical analyses were carried out in order to assess the nonlinear dynamical behaviour of bell tower Pomposa Abbey Codigoro, province Ferrara (Italy), by means Non‐Smooth Contact Dynamics (NSCD) method. The main purpose work is investigate capacity mechanical parameter used analyses, namely, friction coefficient, have effects on response ancient masonry structures undergoing seismic actions. Therefore, was modelled following discrete element method (DEM) and assembling texture as...
The present research paper properly focuses on the dynamics and failure mechanisms of masonry “Apennine Church” Santissimo Crocifisso in Pretare, municipality Arquata del Tronto province Ascoli Piceno (Marche region, Central Italy). Such a peculiar structural type traditionally characterizes intense seismic area Italy, unfortunately almost totally damaged by recent shock sequence 2016. Advanced numerical modeling through discontinuous continuous approaches were here utilized to have an...
This work evaluated the remarkable influence of stereotomy on discrete methods adopted for dynamic response an ancient masonry structure. The historic building used as a case study is Church Santa Maria Varano in Muccia, province Macerata, Italy, which was exposed to severe seismic sequence that hit Central Italy 2016, namely major events Accumoli, Visso, and Norcia. structure modeled using actual blocks three hypothetical arrangements walls investigate existing crack pattern vulnerabilities...
The dynamic behaviour and the seismic vulnerability of ancient civic tower Amatrice, dramatically damaged by last shocks sequence 2016 that occurred in Central Italy, have been studied this paper means advanced 3D numerical analyses with Discrete Element Method (DEM). Thus, a discontinuous approach has used to assess properties masonry structure, through large deformations regulated Signorini's law, concerning impenetrability between rigid bodies, Coulomb's regarding dry-friction model....
Bond patterns influence responses of masonry barrel vaults to mechanical loads. In this research, the discrete element method (DEM) was applied investigate how bond affect static load bearing capacity under vertical The two most widely-used (transverse and longitudinal) were studied. Using a commercial DEM software, 3DEC, with different angles embrace prepared according both patterns, then loaded in three alternative ways until failure. failure loads recorded, compared for each overall...
To begin, the paper introduces methodologies employing both homogeneous continuous Finite Element Method (FEM) and block-by-block Discrete (DEM) to model masonry behaviors. In approach, is modeled as an anisotropic damageable material (homogeneous or not). contrast, block-based approach represents rigid blocks interacting through contact joints governed by frictional cohesive The DEM framework allows for significant displacements, rotations, complete detachments of blocks, aspects often...
The current work presents a hybrid Finite Element Method and Discrete (FEM-DEM) strategy, which combines classical finite discrete element methods in common tool, illustrates its capabilities reproducing the real behavior of masonry during experimental quasi-static tests seismic actions. numerical implementation is available open-source LMGC90 code. In this approach, anisotropic damageable deformable blocks interact each other through contact joints governed by frictional cohesive behaviors....

Thus, a discontinuous approach has used to assess properties structure, through large deformations regulated Signorini’s law, concerning impenetrability between rigid bodies, Coulomb’s regarding dry-friction model....
The preliminary results of an ambient-vibration based investigation conducted on a large sample historic masonry towers in the Marche region (Central Italy) are presented, with focus belfry Collegiata Santa Maria Visso (Italy). assessment procedure includes full-scale ambient vibration testing, modal identification from responses, finite element modeling and dynamic-based uncertain structural parameters model. As most doubtful parameters, modulus elasticity is adjusted to achieve...
Italy is a high seismic risk country since 1900 more than 30 earthquakes with magnitude greater M w =5.8 have occurred, and the last one Central sequence. The first shock occurred in 24 August (Mw=6.2) followed by another stronger quake th October (Mw=6.5). It hit regions of Marche, Umbria, Abruzzo heavily causing many deaths, injuries extensive damages on cultural heritage. This paper analyses church San Francesco Amadola, located Marche region that has been considered condemned for severe...
