Effect of Spatial Variation of Ground Motions on Bridges

by Aspasia Zerva, CCNY, United States,



Document Type: Proceeding Paper

Part of: Probabilistic Methods in Civil Engineering

Abstract:

The effect of spatial variation of ground motions on the response of a two-span bridge is presented. Perfectly and partially correlated earthquake ground motions are used as input motions at the supports of the bridge; mean maximum displacements, bending moments and shear forces along the lifeline are determined through a random vibration analysis. The results obtained indicate that displacements are dominated by the pseudostatic response and that shear forces and moments are, in general, higher for partially correlated motions than for perfectly correlated motions.
