A Historical Survey and Analysis of the Compressive Strength of Brick Masonry
A Historical Survey and Analysis of the Compressive Strength of Brick Masonry
(OP)
Does anyone have a copy of the above paper?
Does anyone have any other recommendations/references for guidelines on allowable stresses in old brick masonry?

It's been awhile, but I think I've always used 100 psi for the allowable bearing stress in brick masonry.

CANEIT - Thanks, that's helpful. I've found people recommending a range of 100psi to 250psi as allowable for bearing.
I saw in an old eng-tips post that someone had mentioned having a copy of the paper I am asking about, I was hoping someone still had it. I'd like to see a study of testing to get a better sense of ranges.

The results of prism tests have shown that mortar has a small effect of the compressive strength of a masonry wall and compressive strengths of the masonry units controls the engineered strength. - The mortar is in a thin horizontal layer perpendicular to the load and any failure is similar to confined compression, so it has little effect.
This may not apply to your needs, but selected units could be sample to determine the approximate strength of the masonry wall. - I have seen hollow masonry prisms with a compressive strength of 5000 psi with 2000 psi mortar. For solid brick, the effects of the mortar strength would be somewhat less.
Sorry, but I do not have a copy of the subject referenced.
