Displacement Of Bridge Abutment Under Earthquake Loading, Yulman Munaf, Shamsher Prakash
International Conference on Case Histories in Geotechnical Engineering
Bridge abutments may experience significant displacements during earthquakes. A two-dimensional model has been developed considering sliding and overturning displacement and 1) strain dependent soil stiffness and soil damping and 2) horizontal and vertical time dependent seismic load. The displacements are computed from the static equilibrium position where the seismic backfill force increments are considered for determining the active earth force acting behind the abutment wall. This means that the permanent displacement increment occurred if the acceleration acts towards the backfill and the abutment wall moves away from the backfill. The total displacement at the top of bridge abutment is calculated …

International Conferences on Recent Advances in Geotechnical Earthquake Engineering and Soil Dynamics
To better understand the causes of pile damages during earthquakes such as Hyogoken-Nanbu Earthquake, shaking table tests of soil-pile-structure interaction models were done using a large scale laminar shear box. Because the pile response is affected by both the ground motion and the structure's inertial forces, three models were test & a soil-pile model and two soil-pile-structure models. For the latter models, superstructures with long and short natural periods were tested separately. Through comparisons among the three cases, the influences on the pile response due to the inertial force of the superstructure for the long and short natural periods were …
