Pulse-like ground motion simulation using wavelet-based Hilbert transforms [PDF]
مهندسی عمران شریف, 2022 In areas near active faults, ground motions usually show a large pulse in velocity time history. These near-field pulse-like ground motions increase the structural failure and cause extensive damage to structures.
