Objective
Ground vibration response Induced by an elevated rail bridge
The elevated rail bridge Consists of hundreds of spans

Summary A periodic method for an elevated rail bridge
Frequency domain A large number of identical spans Linear analysis
Compare to a time-domain dynamic analysis (N spans) The results tend to consistent when the N is larger Vibration of higher frequency differs FE model for the periodic method is much smaller
Summary and possible future work
Possible future work The foundation can be modeled:
Foundation-foundation interaction can be considered
