Near-fault pulse-like ground motions selected from the PEER Ground Motion Database

This dataset contains near-fault ground motion records with velocity pulses selected from the PEER Ground Motion Database. The records were selected by requiring both RJB and Rrup to be less than 30 km. For each ground motion record, peak ground acceleration (PGA) was calculated directly from the acceleration time history. Peak ground velocity (PGV) was obtained by integrating the acceleration time history using the trapezoidal rule, without baseline correction, linear detrending, or filtering. For the two horizontal components of each record, the component with the larger PGV was defined as the H1 direction, whereas the component with the smaller PGV was defined as the H2 direction. The variable swapped_horizontal indicates whether the original horizontal component order was changed. A value of swapped_horizontal = 0 indicates that the horizontal components were not swapped, and Horizontal-1 corresponds to the H1 direction. A value of swapped_horizontal = 1 indicates that the horizontal components were swapped, and Horizontal-1 corresponds to the H2 direction. All acceleration files were converted from the original PEER format into single-column acceleration time histories, and 20 s of zero acceleration was appended at the end of each record to capture residual displacement.
