Vibration of bridges under high speed trains

Frýba L.
pages 23 - +9p., full text

The simple theoretical model explains the dynamic behaviour of railway bridges subjected to high speed trains. The integral transformations of the governing partial differential equation present the deﬂections, stresses and vertical accelerations of the beam model of a bridge in a closed compact form. The numerical solution gives a survey of the effect of various parameters, like speed of trains, span of bridges, damping etc. Moreover, the stress records were classiﬁed using the rain ﬂow counting method and presented the stress spectra which enable the fatigue calculations and life estimations.
