Stability of Rocking Structures

Previous studies on the overturning of rocking structures subjected to earthquake motions have focused on the development of numerical tools to estimate dynamic response.  These tools can be used successfully to estimate the response of a rocking structure but only after systematic calibration against experimental results from tests designed to reproduce accurately the conditions of interest. 

This dataset contains data from 312 earthquake simulations on rocking blocks with various aspect ratios and sizes. The input motions were modeled after six different components of ground motions measured in Japan (Kobe), California USA (Northridge, Chalfant Valley, Mammoth Lakes, Imperial Valley), and Turkey (Duzce).

The test setups were instrumented using two accelerometers, an LVDT, and a set of Optotrak optical markers which measured movement in three dimensions. In addition, a high-speed camera was used to record many tests.
