The dynamic soil-structure interaction effects and spatial variations of a seismic motion seem to have significant contributions on the response evaluation of a long span suspension bridge. Emphasis is placed upon the dynamic response evaluation of a long span suspension bridge subjected to a seismic motion with spatial variations. The dynamic response analysis is carried out using the random vibration approach, which is easily applied to the cross spectral density function which can be evaluated for the spatial variatons of a seismic motion.
