Study on the Simulation of Spatial Variable Seismic Ground Motion Considering Local Site Convergence

Abstract:

By modifying the Random phase angle ,conventional method of ground motion simulation is improved .The simulated result that used conventional method have a good astringency on the limited site and more reasonable to accord with actual state of seismic. To make the simulated result with variability in space and time, simulated progress considered not only the traveling wave effect, but also the spatial coherence of the seismic ground motion and local site effect.
