Investigation Of The Toppling Of Rectangular Rigid Blocks Using A Shake Table And Distinct Element Models, Sara Magallon

Graduate Theses & Non-Theses

Understanding the engineering principles of failure modes in rock formations from seismic activity continues to be a challenging problem for engineers and geologists. The complexity of the geology, geometry, discontinuities, and earthquake ground motions contribute to the difficulty in estimating the stability of rock slopes. In this study, one classic rock slope failure mode is examined: the toppling behavior of a single rigid rectangular block under dynamic loading. An investigation employing experimental and numerical modeling techniques was performed to observe the response of wooden blocks with different aspect (width/height) ratios subjected to loading at the base and compared to established …
