Synthetic regular triangular joints made of gypsum plaster were cyclicly sheared to measure asperity degradation and mathematical behavior of regular triangular joints. Laboratory cyclic shear tests were conducted for three joint types under three different normal stresses. Asperity degradation and shear strength of joints were found to be a function of joint roughness, normal stress, shearing displacement and number of loading cycles. Based on the experimental results, mathematical models were developed for evaluation of shear strength in cyclic loading conditions. Comparison of the test results with that of the proposed model, it was found a good agreement was observed.
