These datasets are from shake table experiments conducted on a series of simply-supported, single-span bridge models with skew angles of 0º, 30º, 45º, and 60º. These experiments were conducted on one of the biaxial shake tables in the Earthquake Engineering Laboratory of the University of Nevada, Reno, from September to November 2015. A total of 876 experiments were performed to investigate the seismic performance of skew bridges. The following data are included in these datasets for each of the 876 experiments: • absolute acceleration (achieved motion) of shake table recorded by table system DAQ in longitudinal and transverse directions (quantity: 2 response histories) • relative displacement of superstructure in longitudinal and transverse directions at each corner (quantity: 8 response histories) • in-plane rotation (quantity: 1 response history) • relative normal displacement of superstructure at each corner (quantity: 4 response history) • impact force at each corner (quantity: 4 response histories) • absolute acceleration normal to and parallel with the abutment at each corner (quantity: 8 response histories) • absolute acceleration at center of mass of the superstructure (quantity: 2 response histories), and • absolute acceleration (achieved motion) of shake table recorded by an accelerometer on the table platen (quantity: 2 response histories). The sampling frequency for achieved table accelerations recorded by table system DAQ was 256 Hz. All other response data were recorded on a high-speed data acquisition system, which had a sampling frequency of 20,000 Hz.
