The spatial variation of seismic ground motions denotes the differences in the seismic time
histories at various locations on the ground surface. This text focuses on the spatial …

Earthquake ground motion spatial variability can influence significantly the response of
certain structures. In order to accurately evaluate probabilistic characteristics of the seismic …

The validity of the response spectrum concept for determining loads in structures excited by
differential earthquake ground motion is examined. It is shown that the common definition of …

Wave passage and differential motions at multiple supports of long structures result in
excessive demands in the near field of strong earthquakes. These demands are caused …

This paper investigates the effect of asynchronous earthquake ground motion on the
transverse response of base-isolated bridges. In this context, the excitation of anti-symmetric …

This paper presents a novel, bridge-dependent approach for quantifying the increase of
design quantities due to spatially variable earthquake ground motion (SVEGM). Contrary to …

It is shown that the common response spectrum method for synchronous ground motion can
be extended to make it applicable for earthquake response analyses of extended structures …

Observations from closely-spaced seismograph arrays since the late 1970's have shown
that earthquake ground accelerograms measured at different locations within the …

It is shown that the pseudorelative spectral velocity (PSV) of an equivalent oscillator, which
can be represented by a single degree-of-freedom system for excitation by synchronous …

The sensitivity of bridges to spatial variations of seismic ground motions is studied within the
framework of the multiple support response spectrum (MSRS) method developed by Der …
