UC San Diego operates the largest outdoor shake table worldwide for earthquake engineering research. This shake table is part of the NEES NSF collaboration initiative. The experiment shown was conducted under a NEESR grant from UNR to explore the seismic loads imposed on bridge structures if the bridge moves into the approach ramp abutments on either end of the bridge.
Do they have sand in there? I don't get how this structure would fit into an approach ramp abutment. Looks to me like a test to see how the soil fails under seismic loading, though I guess I'm probably wrong after reading the description.
