Research on seismic isolation control of long-span mid-supported CFST arch bridge

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...

Historical view of long-span bridge aerodynamics

Some features of bridge aerodynamics of wind engineering are reviewed at this time, in view of the collapse of the Tacoma Narrows Bridge and also to celebrate Professor Alan G. Davenport’s 40 years of contribution to the field. Primary highlighted topics are: description of motion-dependent forces for flutter instability, presentation of gust responses caused by turbulent winds and suppression ...

Pushover Analysis of Long Span Bridge Bents

Influence of apparent wave velocity on seismic performance of a super-long- span triple-tower suspension bridge

As one of the main characteristics of seismic waves, apparent wave velocity has great influence on seismic responses of long-span suspension bridges. Understanding these influences is important for seismic design. In this article, the critical issues concerning the traveling wave effect analysis are first reviewed. Taizhou Bridge, the longest triple-tower suspension bridge in the world, is then...
