WebFeb 21, 2011 · Masonry exhibits a brittle behavior when subjected to tensile loading; the corresponding tensile strength is quite low and, for design purposes, can be neglected. The shear strength of masonry depends on the level of applied axial load, as it relies upon cohesion and friction of the material.
WebCodes of Practice relate modulus of elasticity to characteristic strength or specified compressive strength of masonry, which is dependent on unit strength and mortar strength. In addition, there are other methods for estimating modulus of masonry from only strength of the unit. This chapter reviews the stress–strain behaviour and identifies ...
