The seismic design of structures considers that all ground supports are subjected simultaneously to identical seismic excitation. This assumption is not valid for extended structures since it has been recognized that seismic motion exhibits no negligible variability. The spatial variation of seismic ground motions denotes the differences in the seismic time histories at various locations on the ground surface.

A Note on Spatial Variations in Response Spectra of Earthquake Ground Motions earthquake-resistant structures. However, since the regression analysis was made by using data from many earthquakes simultaneously, residuals included intra-event as well as inter-event variability.

The evaluated spatial variation characteristics of seismic motion were used to derive statistical models based on regression analysis. The results showed that coherency decreased with increasing frequency and distance. Meanwhile, variation in Fourier amplitude ratio increased with increasing frequency and distance below 5 : Osamu Uchida, Hirotoshi Uebayashi, Katsuhiro Kamae.

In recently years, many sea-crossing bridges were built in some countries.
