Estimation of strong seismic ground motion for engineering use in Perth Western Australia
Probabilistic seismic hazard analysis (PSHA) was performed to determine two alternate magnitude-distance combinations for the 475 yr event, and the worst-case scenario event in Perth, Western Australia. Regional strong ground motion (SGM) time histories on rock sites are used to modify an eastern No...

| description | Probabilistic seismic hazard analysis (PSHA) was performed to determine two alternate magnitude-distance combinations for the 475 yr event, and the worst-case scenario event in Perth, Western Australia. Regional strong ground motion (SGM) time histories on rock sites are used to modify an eastern North America (ENA) seismic model to suit southwest Western Australian (SWWA) conditions. This model is then used to stochastically simulate a set of 475 yr design events and a set of worst-case scenario event for rock sites in the Perth metropolitan area (PMA). The simulated time histories are then used as input to typical soft soil sites in the PMA to estimate surface ground motions. The spectral accelerations of the ground motions on rock and soil sites are calculated and compared with the corresponding design spectra defined in current and previous Australian earthquake loading code. Discussions of the adequacy of the code spectra and the differences to ours, along with implications on structural response and damage are made. © 2008 Elsevier Ltd. All rights reserved. |
