Stack bonded masonry is scarcely used in practice, except for aesthetic reasons. Nevertheless, a regular array of units allows placing reinforcement in the joints, which can be of major importance for masonry shell roofs, as proposed by Eladio Dieste, a Uruguayan engineer who designed several innovative curved masonry shells for roof and walls. In order to contribute to knowledge of the behaviour of stack bonded masonry under shear loading, which seems not to have been addressed before, an experimental research programme using the triplet test was carried out. The specimens incorporate aligned joints along two orthogonal axes, filled with micro-concrete. The main results are presented and discussed. 15 refs.
