Earthquake resistance of clay block masonry

In design of structural masonry in compliance with EN 1998-1 and EN 1996-1-1 provisions, the earthquake resistance is considered as shear resistance. Therefore it relies on adhesion developed between the masonry units and mortar bed joints. The shear resistance is determined equally regardless of the group of masonry units from which masonry is constructed from. However, in construction of clay block masonry, during placement of masonry units and mortar, intrusion of mortar into clay block voids occurs. For this reason, the failure of masonry in shear occurs when masonry unit tensile strength is exceeded, instead of sliding over the mortar bed joints. This paper gives the results of experimental investigation on clay block masonry shear resistance in direction of mortar head joints and bed joints. For the purpose of design for earthquake resistance of structural clay block masonry, mathematical expressions were recommended which take into account the clay block masonry unit and mortar joint interlocking.
