Seismic response analysis of jointed rock slope under pulse-like ground motions
Advances in Civil EngineeringAbstract Because of the directional effect, energy concentration and hanging wall effect of pulse-like ground motions, it is easy to cause rock fall, collapse, and landslide of jointed rock slope. To reveal the deformation law and failure model of jointed rock slope under pulse-like ground motions, a discrete element numerical model of ...

Rigid Structure Response Analysis to Seismic and Blast Induced Ground Motions
Procedia Engineering, 2011 AbstractComprehensive studies of rigid structure responses to seismic ground excitations have been reported. It was found that the rocking and sliding response of a rigid structure is highly nonlinear. The structure stability depends on the structure slenderness, as well as the ground motion amplitude, frequency and duration.
