A numerical study of six test methods that have been used to measure masonry joint shear strength indicates that, of these, the Hofmann/Stockl test is theoretically the best. It is not, however, suitable for adoption as a standard test method because it requires the use of complex testing apparatus. Of the other test methods, the triplet test with minimum bending is as good as any. A new test method is suggested which should be capable of producing results better than any of the methods studied, even though it needs only relatively simple equipment.
