Time-dependent Behaviour Analysis of Long-span Concrete 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 ...

Pushover Analysis of Long Span Bridge Bents

Experimental Modal Analysis of a Concrete-filled Tube Arch Bridge

This paper presents the experimental and analytical modal analysis of a concrete-filled (CFT) tube half-through arch bridge, with the span length of 90m, located at the center of Xining City, Qinghai province, China. Dynamic field test was carried out just prior to the official opening of bridge in order to inspect the dynamic characteristics of the bridge and make a baseline record for the fut...

Design and implementation of a monitoring system applied to a long-span prestressed concrete bridge

Currently long-term monitoring systems are mandatory in major civil engineering structures like bridges, tunnels and dams. Generally, they monitor a set of physical, chemical and mechanical parameters in critical sections of the structure by incorporating appropriated sensors. The set of collected data demonstrates great potential in the prevention of damage and contributes to a more efficient ...

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 ...
