Displacement monitoring of a Long-Span Arch Railway Bridge using Digital Image Correlation (DIC)

There is an escalating demand for condition monitoring enhancement of transport infrastructures worldwide. Bridges are of vital importance in transportation infrastructure and need such monitoring. In this research, a non-contact vision-based technique called Digital Image Correlation (DIC) was used to calculate the bridge displacements. A high frame rate camera with 4K capability was used for ...

Application of Structural Damage Control in Seismic Performance Opti- mization of Long-span Cable-stayed Bridge

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...
