Study of the compressive response of masonry using non-conventional joint materials

Winner of the International Journal of Masonry Research and Innovation IJMRI Best Paper Award 2017The compressive response of masonry is influenced by geometric, material and execution variables. In addition, the nature of bricks and mortar typically introduces uncertainty to the experimental results. In order to reduce this uncertainty, an experimental campaign has been carried out to analyse the influence of the properties of the joints. Four non-conventional masonry typologies including resin, EPS and rubber joints have been considered for this purpose. In all, 60 compressive tests and 50 deformability tests on five stacked bricks prisms were performed. Obtained data are compared with data from the literature. A comparison with the current European standard is also carried out. The obtained results point out that the modulus of linear deformation of the joint is the most influent variable on the compressive response of masonry. Finally, it seems that current formulation (Eurocode-6) tends to overestimate the modulus of linear deformation of masonry.Peer ReviewedAward-winnin
