Investigation and control of vortex-induced vibration of twin box girders
Journal of Fluids and Structures, 2013Abstract Stationary and dynamic wind tunnel tests of twin box girders with a space ratio of L/D=1.70 have been performed in this study. The vortex-shedding phenomenon under stationary and dynamic conditions and vortex-induced vibration are observed and analyzed. The results indicate that regular vortex shedding occurs only at the trailing edge of the

Aerodynamic Stabilization Mechanism of a Twin Box Girder with Various Slot Widths
Journal of Bridge Engineering, 2015Five representative girder cross sections with various slot widths are utilized to analyze the effects of center slots on their aerodynamic performance, based on wind-tunnel tests and theoretical analyses. It is shown that the favorable aerodynamic effects of the center slot on bridge decks depend on the aerodynamic shape of the box girders and on the ...

Aerodynamic instability performance of twin box girders for long-span bridges
Journal of Wind Engineering and Industrial Aerodynamics, 2015Abstract Twin box girders are a popular choice among long-span bridge engineers, and the aerodynamic performance of such a system is critical to the stability of a bridge under wind excitation. Two groups of twin-box girders with six representative slot width ratios varying from 0% to 100% were utilised to investigate the influence of different wind ...

Investigation of free vibration and ultimate behavior of composite twin-box girder bridges
Journal of Constructional Steel Research, 2017Abstract Multi spine composite concrete-deck steel-box girder bridges became a very popular choice in highway bridges due to their high torsional and wraping stiffness as well as for economic and aesthetic reasons. This study presents an experimental investigation on both elastic and ultimate behavior of composite box girder bridges in order to study

The 1915 Çanakkale Bridge: Designing a twin-box girder suitable for a world record span
IABSE Reports, 2023<p>Optimization is the key to the success of any long span suspension bridge. Since the deadload covers up to 80% of the utilisation of the expensive main cables, keeping the weight of the girder down is essential. For the 1915 Canakkale bridge the twin-box girder design was introduced to ensure suflicient aerodynamic performance, but with a ...
