Abstract

An experimental investigation of compressive failure in masonry made of soft clay bricks is presented. Damage evolution associated with the formation and propagation of vertical splitting cracks during the compressive load response of masonry assemblies in the stack bonded arrangement is evaluated. Full-field surface displacements during the compression load response of the masonry are obtained using digital image correlation (DIC). A clear evidence of the crack forming in the mortar and propagating into the brick is established. In mortar with lower strength than the brick unit, failure is produced by spalling associated with multiple vertical cracks, which result in loss of load bearing area. For mortar with a higher strength than the brick, cracking occurs when the level of compression is a significant proportion of the compressive strength of the brick. Failure is a result of global instability produced by the localized crushing of the brick. INVESTIGATION OF COMPRESSION FAILURE IN BRICK MASONRY ASSEMBLIES MADE WITH SOFT BRICK.
