Importance of 1-point statistics in earthquake source modelling for ground motion simulation

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 ...

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...

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...

Simulation of artificial earthquake records using Point Source method with applying amplification effects

Today to design large hydraulic structures like dams, application of dynamic analysis in time domain seems very interesting due to its benefits. For applying such analysis, appropriate earthquake records that are compatible to site conditions are necessary for designer. Such information is rarely recorded for a dam site during an earthquake and usually the amount of recorded data is not suffici...
