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

Numerical Investigation of Tsunami Wave Force Acting on Twin Box-Girder Bridges
Earthquakes in coastal areas frequently trigger tsunami waves, posing significant threats to low-lying coastal bridges. Investigating extreme wave force on bridge deck is crucial for understanding bridge damage mechanisms.

Numerical simulation and validation of local wind environment of twin-box girder with wind barriers
Computational fluid dynamics (CFD) was used to reproduce wind fields around a twin-box girder. Wind tunnel tests and field measurements were conducted to verify the accuracy of the CFD results.

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

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