The objective of the research described in this paper is to validate the analytical models proposed by Gibson et al. by performing laboratory experiments using a shake table.

1) creating blocks representing Gibson’s two-dimensional parallelograms with three-dimensional printing material,

2) using Montana Tech’s shake table to subject the blocks to increasingly higher accelerations until failure (sliding, slumping, or toppling) is observed, and

3) comparing the observed and predicted modes of failure.
