Abstract: The operational performance of high-speed railway bridges is controlled by stiffness, and the reduction in bridge stiffness leads to a decline in ride comfort. Therefore, it is very important to periodically evaluate the ...

Abstract: The bridge influence line (BIL) contains static information for each section of a bridge, which is an important tool for bridge design and condition evaluation. The current influence line identification procedure relies ...

Abstract: Girder rotation at the bridge support or girder end is a key deformation indicator that reflects the high-speed railway (HSR) bridge stiffness. Large rotation deformation at these locations leads to train derailment risks, ...

Abstract: With an increase in bridge service time, damage will inevitably occur. Accurately identifying damage is of great significance to the operation and maintenance of a bridge. To realize a frequent identification of local ...

Abstract: Sliding bearings are a key component of bridges, and their normal performance is an important prerequisite to ensure traffic safety. To solve the problem wherein a single type of sensor has difficulty in effectively ...
