WebSep 1, 2024 · The VIV of the railway girder only occurs when it is located upstream, and the amplitude is small, while the highway girder has a different large vertical VIV whether it is located upstream or downstream, and the VIV performance is poor. The maximum amplitudes of vertical VIV for both highway and railway girders all occurred at α = 3°. The … The earliest rails were simply lengths of timber. To resist wear a thin iron strap was laid on top of the timber rail. This saved money as wood was cheaper than metal. The system had the flaw that every so often the passage of the wheels on the train would cause the strap to break away from the timber. The problem was first reported by Richard Trevithick in 1802. The use of strap rails in the Uni…
