Abstract
Monuments, equipment, chimneys, and older intake structures for dams all may rock during strong ground motions. These and other rocking objects are vulnerable to overturning, leading to potential economic loss and disruption to affected communities. The need for methods to estimate rocking response is supported by the breadth of structures susceptible to overturning and their prevalence in the built environment. Previous research on the development of numerical tools for the simulation of rocking behavior in response to earthquake motions has shown that simulation results are highly sensitive to input parameters, and that data from experimental tests are needed to calibrate these tools. To provide such test data, 312 experiments were conducted on unanchored concrete blocks on an earthquake simulator. The tests were instrumented using accelerometers and a three-dimensional (3-D), noncontact optical tracking system. All data are available online and can be accessed via DOI: 10.4231/R7FB513S and in interactive form at datacenterhub.org/resources/14255 . Two simple examples are provided to show how the data may be used. Readers are encouraged to use the data as a means for evaluating more detailed methods to evaluate rocking response.
