Abstract
In a time when ensuring the safety of existing buildings according to modern standards is paramount, evaluating the stability of masonry structures against hazards poses a significant challenge. While masonry is known for its versatility and durability, issues such as insufficient material property data, irregular geometries, and aging complicate structural assessments. To address these challenges, various modeling techniques have been developed through extensive scientific research. This paper critically examines innovative approaches, focusing on a comparison between the Finite Element Method (FEM), a continuous approach, and the Discrete Element Method (DEM), a discontinuous approach, applied to a case study impacted by the 2016 Central Italy earthquake. The FEM is analyzed using Midas FEA NX©, while the DEM is explored with 3DEC© and LMGC90© software, utilizing different contact conditions. The study reveals the strengths and weaknesses of each method: the DEM excels in accurately replicating failure patterns, whereas the FEM offers a quicker setup process, making it suitable for preliminary dynamic analyses of structures..I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
