Elastic modulus and strength of hollow concrete block masonry with reference to the effect of lateral ties

This paper presents the results of an experimental investigation to derive a formula for the short-term static modulus of elasticity Em of unfilled andfilled concrete blockwork masonry. The formula is based on the modulus of elasticity of each individual material used in the construction of blockwork masonry. The effects of using lateral ties as reinforcement on the behaviour, ductility and strength of concrete blockwork masonry are also investigated.
