WebApr 3, 2013 · The range of the mean Poisson’s ratio is 0–0.14 at 30 % of the load-to-strength ratio and 0.07–0.22 at the end of the quasi-elastic stage. The values obtained are of the same order of magnitude as those obtained by Bosiljkov et al. [ 11] for masonry specimens made with cement-based mortar. Weblateral strains in the bricks, due to Poisson’s effect, are enhanced by the brick expansion due to moisture uptake. The contribution of the mortar joints to the global creep of masonry is discussed by Sayed-Ahmed et al. [20]. According to the results of the experimental program mentioned above, they found that the joints are
