Effects of soil-structure interaction on the seismic response of cable-supported bridges FLBetti*, A.M. Abdel-GhafW "Department of Civil Engineering and Engineering Mechanics, Columbia University, New York, NY i> Department of Civil Engineering, University of Southern California, Los Angeles, CA 90089, USA ABSTRACT The dynamic soil-structure interaction effects on the response of long-span cable-supported bridges subjected to traveling seismic waves are presented in this study. The foundation system is represented by multiple embedded cassion foundations and the interaction analysis includes both the inter- action between the foundations and the surrounding soil and the cross- interaction among adjacent foundations. To illustrate the potential imple- mentation of the analysis, a numerical example is presented in which the dynamic response of the Vincent-Thomas suspension bridge (Long Beach, CA) subjected to the 1987 Whittier earthquake is investigated. Although both k
