The study of strength and the curved stress/strain relationship of blockwork
masonry walls is basic for the material characterization and the development of
structural analysis of blockwork walls. This work deals with that subject, aiming at the
evaluation of the main elastic parameters and the strength of concrete blockwork walls:
the compressive strength and modulus of elasticity for masonry in two orthogonal
directions, parallel and perpendicular to bed joints.
An experimental program was developed to evaluate the influence of the
strength of blocks and mortar, and the load application direction on the mechanical
behavior of ungrouted concrete block masonry under compression. A series of
laboratory tests was carried out with blocks, mortar, prisms of three blocks and wallets
(80 cm x 80 cm).
It was impossible to obtain acceptable correlations of the defined variables, usin
statistical inference. However, tendencies of the specimens behavior were obtained,
confirming the influence of mortar and block properties on the structural behavior of
concrete blockwork walls under compression.
Keywords: Blockwork masonry, compressive strenght, compression tests, concrete
blocks, modulus of elasticity, stress-strain curves.
