Discontinuities, ie, joints, bedding planes, contacts and faults (ISRM 2007), are widely developed in rock masses. The assessment of the shear strength of these discontinuities is very important for evaluating the stability of rock structures, so lots of researches have been carried out on this aspect (ie, Patton 1966; Barton 1973; Barton and Choubey 1977; Grasselli and Egger 2003; Guo and Qi 2015; Zheng and Qi 2016). In addition to static shear loads, also dynamic shear loads, eg, seismic wave loads, which are rapid and cyclic loads, need to be considered (ie, Li et al. 2011, 2014).The shear strength of discontinuities under dynamic cyclic shearing is expected to decrease gradually (ie, Crawford and Curran 1981). Therefore, a rock structure which is stable under static loads may move or slide along the discontinuities and co-seismic landslides or other instabilities may occur during strong earthquakes (ie, Qi et al. 2010, 2011, 2015). Hence, the shear behavior of discontinuities under dynamic cyclic shearing should be properly investigated (Dang et al. 2016; Fathi et al. 2016).
