Spatial Variability Effects on the Seismic Response of Models of Bridges

by Aspasia Zerva, Drexel Univ, Philadelphia, United States,



Document Type: Proceeding Paper

Part of: Probabilistic Mechanics and Structural and Geotechnical Reliability

Abstract:

The significance of the spatial variability (spatial incoherence and apparent propagation) of the seismic ground motions on the response of bridges, modeled as three-span symmetric beams, is analyzed. It is shown that spatially variable seismic ground motions induce significantly higher bending moments along the structure than the ones obtained if the seismic motions at the supports are assumed to be identical.
