Resonance and criticality measure of ground motions via probabilistic critical excitation method

摘要

Resonant characteristics of recorded ground motions are investigated and a measure of criticality of ground motions is proposed. Four classes of recorded ground motions, i.e.,(i)near fault motions(rock records),(ii)near fault motions(soil records),(iii)long duration motions (rock records)and(iv)long duration motions(soil records), are taken from Abrahamson N, Ashford S, Elgamal A, Kramer S, Seible F, Somerville P, Proc of First PEER Workshop on Characterization of Special Source Effects, 1998.
