If there is a special case where tensile forces are expected, for example a retaining wall, or a mid-rise structure, or earthquake load, the engineer will specify the the masonry is reinforced with steel and then it can resist tension through the unit/mortar interface just fine.
It is a poor structural engineer who tells the architect masonry isn't an option because tension.
Can anyone confirm?
