This is my senior research project from when I attended Roanoke Valley Governor's School. It's called an Earthquake Simulation Table or shake table for short. Basically what it does is reproduce waveforms of similar frequency to earthquake shear waves and of equivalent scaled amplitudes. The oscillating motion is only in the x and y axes, but the simultaneous motion in both axes can create different paths. The top stage is 4 sq.ft. with holes for attaching structures to be tested using clecos. Credit for helping build the machine goes to my brother and design advice goes to my project adviser.
