"Seismically Induced Lateral Earth Pressures: An Update"
Presented by: Professor Nicholas Sitar
M
ethods for evaluating the seismically induced lateral earth pressures gradually evolved from the seminal Japanese work
performed in the 1920’s. The resulting design procedures suggest large dynamic loads during strong ground motion. However
field evidence from recent major earthquakes fails to show any significant problems with the performance of retaining structures
designed for static earth pressures only. Similarly, the results of recent and ongoing centrifuge experiments indicate that seismically
induced lateral earth pressures are significantly less than those estimated using the most current design methods based on the
Mononobe-Okabe assumptions. The presentation will focus on latest results from centrifuge model studies and recent observations
in large earthquakes, and their implications for a rational seismic design of retaining structures and basement walls.
