Dynamic Analysis of Railway Bridges Considering the Nonlinear Amplitude-Dependent System Behaviour - Simulation and in-Situ Tests
Michael Reiterer,
Andrei Firus
Abstract:The train-induced forced vibration responses of railway bridges are investigated and evaluated under consideration of nonlinear effects. The considered nonlinearities refer to the amplitude dependency of the natural frequencies, which was observed during in-situ measurements conducted by the authors for several existing railway bridges of different construction type. The nonlinearities detected during dynamic measurements on existing railway bridges are presented and discussed. The focus is on single-span stee… Show more
