Abstract:This paper focuses on assessing the effect of two different structural bonding patterns on clay brick masonry assemblage mechanical characteristics under compression, flexure, and shear loading conditions. 2D-digital image correlation technique (DIC) used to appraise the nonlinear compressive stress-strain characteristics, orthotropic properties, damage, and failure mechanisms of masonry prisms. The experimental investigation ascertained that full-brick thick masonry exhibited reasonably higher capacity and deformation characteristics than half-brick thick masonry under compression, flexure, and diagonal compression loadings except in bed joint shear strength determination. The compressive strength and corresponding strain of full-brick thick Flemish bond prisms were higher and observed more deformable (maximum strain recorded 2.4 times) behavior than half-brick thick masonry prisms. The failure mechanics of masonry was quantitatively established by strain analysis obtained from DIC. The rupture modulus of Flemish bond masonry walls was higher (4 times), and failure (combination of tensile splitting of bricks and bed joint failure) was gradual compared to stack bond masonry. The diagonal compression strength of full-brick thick masonry wallettes was about 1.3 times running bond wallettes as the bond arrangement resisted the diagonal cracks propagation. The applicability of the available idealized compressive stress-strain analytical models was evaluated, and few improvements were recommended. The research study assessed that due attention needs to be given to structural bonding patterns in evaluating the mechanical characteristics of masonry required in the design and analytical modelling of masonry constructions. DIC technique can be conveniently used to capture the nonlinear strain characteristics and can be handy in detecting the damage early.
