... earthquakes. If the shear loading on rock discontinuities due to actual earthquakes is to be considered, the displacement response must be used as the frequencies of accelerations are extremely difficult to simulate in available equipments. However, as shown by Aydan and Ohta (2011) or Aydan et al. (2011...
