In particular, the behaviour of the interfaces connecting, brick and mortar, are of key importance during seismic actions. This is because the unit-joint interface may act as the main plane of weakness in the masonry composite. It has been observed that the inelastic behaviour of masonry structural elements subjected to shear loading depends largely on this interface behaviour. Hence, different experimental techniques available to observe in-situ or in a laboratory the behaviour of masonry under shear loading are reviewed and a suitable experimental campaign, also employing DIC as optical monitoring system is undertaken and shear tests are performed. After visualisation and discussion of novel displacement and shear strain maps and graphs, the experimental masonry behaviour is replicated via different numerical models based on the finite element approach. Models are used for better characterising the behaviour of the interface between brick and mortar. Further, the main parameters affecting the numerical models are discussed.The experimental part of this research work has received financial support for materials by the European Commission through the FP7- ENV-2007-1 research project “SMooHS - Smart Monitoring of Historical Structures”, (2008–2011) under grant 212939. The experimental facilities and technical personnel of the LISG laboratory of DICAM Department and of CIRI-EC lab both of the University of Bologna are acknowledged. The modelling part of this work was partly financed by FCT/MCTES through national funds (PIDDAC) under the R&D Unit Institute for Sustainability and Innovation in Structural Engineering (ISISE), under reference UIDB/04029/2020.ElsevierUniversidade do MinhoGajjar, Pratik NareshGabrielli, ElenaMartin-Alarcon, Dafne CarolinaPereira, João MiguelLourenço, Paulo B.Colla, Camilla2021-122021-12-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://hdl.handle.net/1822/74310engGajjar, P.
