Abstract
This study analyzes the sensitivity of the response of buried pipelines and above-ground lifelines when different models are used to describe the spatial variability of the seismic ground motions at their supports. Differential displacements and differential response spectra are developed from spatial incoherence models commonly used in lifeline earthquake engineering, and the contribution of the models to the quasi-static and dynamic response of the structures is compared. It is shown that the spatial variability models induce different lifeline response and that the differences correlate with the degree of exponential decay of the models with separation distance and frequency.
