Abstract
The effect of the spatial variation of seismic motions on the response of lifelines is analyzed. Simulations based on the most commonly used spatial variability models are generated and the correspondence between the characteristics of the models and those of the space-time simulations is identified. The effect of the exponential decay describing the loss of coherency in the spatially variable motions on the seismic response of lifelines is evaluated. It is shown that seismic ground motions that are partially correlated at low frequencies induce the highest quasi-static internal forces in lifelines, whereas motions with slowly decaying coherency produce the highest contribution to the dynamic response.
