The commercial operation of the bullet train in 1964 in Japan marked the beginning of a new era for high-speed railways. Because of the huge amount of kinetic energy carried at high speeds, a train may interact significantly with the bridge and even

The soil vibration induced by high speed trains is a problem of increasing importance in engineering practice. Such a problem will be investigated by a finite/infinite element approach in this paper. To simplify the physical simulation of the problem

The aim of this article is: (1) to formulate the bridge-induced dual resonance on a moving train with wave transmission; (2) to establish the dispersion relation of wave transmission in periodically linked cars using the Floquet-Bloch theorem; (3) to

Constant moving load models are widely adopted in the dynamic analysis of railway bridges under moving trains. However, the use of this simple model may overestimate the resonant response of simply supported bridges if the vehicle-bridge interaction

In this paper, the modal coupling mechanism is studied of a single-span footbridge consisting of a suspended beam (i.e., bridge deck), two suspension cables (via hangers) and two wind guys (via wind ties). To start, the governing equations for the sl

A moving impulse load generated by a heavy cogwheel can be used as a testing excitation for bridges. This novel type of dynamic load acts along the entire driving path, its intensity is adjustable, and it can be very efficient in the case of resonanc

This paper presents a new Moving Internal Node Element (MINE) method for the dynamic analysis of bridges/beam structure under a moving load/vehicle. By introducing a moving internal node within the standard beam element, the resulting MINE method eli

For a train composed of a number of identical cars moving over a bridge at high speeds, train-induced resonance on the bridge may occur when any of the frequencies of the bridge coincides with any of those implied by the wheel loads. On the other han
