This report presents an analysis of the results of the tests described in the report "Cyclic shear tests of masonry piers, Volume 1 - test results," by Mayes, Omote, and Clough, May 1976 (UCB/EERC-76/08). The critical tensile strengths obtained from double pier tests are compared with those obtained from a simple diagonal compression test on a square panel. The report also contains idealized hysteresis envelopes developed from the experimental results for the two primary modes of failure observed in the test series. Also included in this chapter are theoretical methods for calculating the ultimate shear and flexural capacities of the piers. The capacities obtained from the theoretical methods are compared with the experimental results; good agreement is obtained for the flexural capacity, whereas the method used for the shear mode of failure overestimates the experimentally determined values. The results obtained in this test program are compared with those of other investigations.
