Dynamic Deflection Measurement on Stiff Bridges with High Piers by
Due to its low cost and high accuracy, the proposed method has broad application prospects in the dynamic deflection measurement of stiff bridges with high piers.
Development of design and construction of high-speed railway bridges
Abstract Bridges are vital components of high-speed rail (HSR) lines for crossing obstacles such as valleys, rivers, and existing highways or railway lines. The main goal of this paper
Effects of expansion devices and dampers on additional forces in a
In the present study, the effects of expansion devices and dampers on the additional forces of continuously welded rails (CWRs) are investigated on the basis of the Wufengshan Yangtze
Analysis of Dynamic Response of Simply-Supported Girder Bridge in
The vibration theory of beam and D''Alembert principle are used to set up vehicle-bridge system for a simply-supported girder bridge under the moving rows mass-spring model.

High-speed train–track–bridge dynamic interactions – Part I
Abstract This paper presents a framework to systematically investigate the high-speed train–track–bridge dynamic interactions, aiming to provide a method for analysing and assessing the
Aerodynamic performance and dynamic response of high-speed trains
High-speed trains (HSTs) passing by each other on cable-stayed bridges (CSBs) generated aerodynamic forces that significantly reduced the operational safety and stability of the trains.
HIGH-SPEED RAIL BRIDGE SYSTEMS
High-speed railway bridges are subject to complex vehicle loading and stringent serviceability cri-teria, which lead to structural solutions different from those used for highway bridges or conven-tional
Design and control of high-speed railway bridges equipped with an
Potential for service life extension of new and existing bridges by retrofitting. Abstract This work investigates the application of an external adaptive tensioning (EAT) system for high-speed
Effects of the highway live load on the additional forces of the
Abstract High-speed running trains have higher regularity requirements for rail tracks. The track-bridge interaction of long-span bridges for high-speed railways has become a key factor for
