The track–bridge interaction is a fundamental concern in the field of railway engineering, which plays an important role optimization design bridges, especially for heavy-haul and high-speed bridges. This paper systematically introduces research status CWR large-span bridges China. evolution process model from simplest elastic bar linear longitudinal resistance to complex beam–rail considering ...

The damage caused by earthquake is irresistible for human beings, and the structure with poor robustness is most affected by earthquake. Especially when traffic arteries like bridges and highways are affected, the losses will be unimaginable. To reduce the loss in earthquake, the paper targets the long-span cable-stayed bridge and discusses a method of structural damage control. The energy-diss...

This paper provides a variety of viewpoints to illustrate the mechanism of the deck-stay interaction with the appropriate initial shapes of cable-stayed bridges, which is validated by a symmetrical structure. Based on the smooth and convergent bridge shapes obtained by the initial shape analysis, the one-element cable system (OECS) and multi-element cable system (MECS) models of the symmetric h...

The traditional manual measurement methods are time-consuming and error-prone when they used for cable-stayed bridges’ geometric dimensions acquisition. They always limited by various adverse conditions such as large bridge spans, the high height of towers, more risk operation, many other unpredictable factors. In contrast, three-dimensional (3D) laser scanning technology is extremely useful so...
