Aerodynamic characteristics of a streamlined box girder under shear flow considering oncoming turbulence

The Physics of Fluids, 2023
Non-synoptic winds, such as typhoons and downbursts, are frequently characterized by shear flow associated with turbulence, which affects the aerodynamic performance of long-span bridges.

Experimental and numerical investigation on wave impacts on box-girder bridges

Structure and Infrastructure Engineering, 2022
Climate change could result in more extreme weather events and induce increasing challenges to the low-lying coastal bridges. The structural performance of box-girder bridges under wave impacts was seldom investigated. In this paper, a three-dimensional (

Investigation on aerodynamic force nonlinear evolution for a central-slotted box girder under torsional vortex-induced vibration

Journal of Fluids and Structures, 2021
Central-slotted box girders are widely employed in long-span bridges owing to their advantageous flutter stability. However, the existence of a central slot can degrade their performance under vortex-induced vibrations (VIVs).

Residual performance and damage mechanism of prestressed concrete box girder bridge subjected to falling heavy object impact

Structure and Infrastructure Engineering, 2022
Extreme vertical impact loading from dropped heavy cargo or falling rocks threatens the safety of bridge structures. The impact behavior and post-impact performance of a multi-piece prestressed concrete (PC) box girder bridge were investigated through ...

Innovative Box girder having Footpath at Bottom of Box girder by Cantilevering Soffit slab

IABSE Congress Reports, 2023
<p>Innovative structural forms for medium span bridges are a challenging effort for bridge design engineers especially in built-up area locations, where social impact plays a crucial role. Box girders are flexible forms compared to conventional ‘I’ girders, in the sense that they can have curved plan as well as varying shape of cross sections ...

Experimental study on characteristics of vortex-induced vibration of a twin-box girder and damping effects

Journal of Fluids and Structures, 2021
To investigate the characteristics of vortex-induced vibration (VIV) of the twin-box girder, we carried out the VIV wind tunnel tests. The VIV of the twin-box girder occurs in the range of 4.680 ≤ U r ≤ 6.113, with the maximum dimensionless VIV ...
