The Effects of Aerodynamic Interference on the Aerodynamic Characteristics of a Twin-Box Girder [PDF]

open access: yesApplied Sciences, 2021
To investigate the aerodynamic characteristics of a twin-box girder in turbulent incoming flow, we carried out wind tunnel tests, including two aerodynamic interferences: leading body-height grid, and leading circular cylinder.

Effects of External Cross-Frames on the Ultimate Behavior of a Twin Steel Trapezoidal Box-Girder Bridge

open access: yesApplied Sciences, 2023
In the construction of a twin-steel box-girder bridge, external cross-frames are temporarily used to increase torsional resistance. These members are regarded as secondary and are removed after a composite action in the bridge is achieved.

Passive Control of Ultra-Span Twin-Box Girder Suspension Bridges under Vortex-Induced Vibration Using Tuned Mass Dampers: A Sensitivity Analysis

open access: yesBuildings, 2023
Suspension bridges’ in-plane extended configuration makes them vulnerable to wind-induced vibrations. Vortex shedding is a kind of aerodynamic phenomenon causing a bridge to vibrate in vertical and torsional modes.

Flutter characteristics of twin-box girder bridges with vertical central stabilizers [PDF]

open access: yesEngineering Structures, 2017
Abstract It has been well known that Vertical Central Stabilizers (VCS) have the potential of improving flutter performance of long-span bridges. However, the fundamental flutter mechanisms of VCS are still not fully understood so far. In this study, a series of wind-tunnel tests involving the combination of six representative heights and four types ...

Influence of earthquake angle on seismic performance of concrete highway bridges

open access: yesGrađevinar, 2023
This study aims to evaluate the effect of earthquake angle on the seismic performance of a concrete highway bridge. As a numerical example, a twin prestressed concrete box-girder highway bridge was analysed using finite element methods.

Path Planning and Control of a UAV Fleet in Bridge Management Systems

open access: yesRemote Sensing, 2022
Traditional methodologies for precise inspection of bridges (pavement, beams, column cap, column, joints and inside box girder, etc.) with By-bridge equipment, Aerial Work Platform (AWP) or via ropes have several limits that can be overcome by using ...
