SIMULATION OF EARTHQUAKE GROUND MOTION USING 3 DIMENSIONAL UNDERGROUND STRUCTURE MODEL DEDUCED FROM GRAVITY ANOMALY

Stochastic Model for Earthquake Ground Motion Using Wavelet Packets

For performance-based design, nonlinear dynamic structural analysis using various types of input ground motions is required. Stochastic (simulated) ground motions are sometimes useful as input motions, because their properties can be varied systematically to study the impact of ground-motion properties on structural response, and producing large numbers of ground motions is simple. This paper d...

Earthquake Ground Motion

Simulation of earthquake rupture process and strong ground motion

Computer simulation of the strong ground motion generated from the earthquake•rupture process on a shallow strike-slip fault are carried out by using a 3-D finite difference method. The faulting process is modeled using a dynamic crack model with fixed rupture velocity or with finite-stress-fracture criterion. The near-source ground motion is sensitive to the details of sliprate or slip-acceler...

New source spectral model and strong ground motion simulation of the 1994 M6.7 Northridge earthquake

ABSTRACT: This paper checked, appended and corrected the strong motion database of Western U.S. on site conditions and so on first, and then recommends a new source spectral model and model parameters depending on the statistical analysis to acceleration Fourier spectra of these strong motion recordings. The new source spectral model has some further improvement to Brune ω 2 model and Atkinson ...

Analysis and Simulation of Earthquake Strong Ground Motion for Earthquake Engineering Applications (2003-2004)

The objectives of this task are to conduct research on seismic hazards, and to provide relevant input on the expected levels of these hazards to other tasks. Other tasks requiring this input include those dealing with inventory, fragility curves, rehabilitation strategies and demonstration projects. The corresponding input is provided in various formats depending on the intended use: as peak gr...
