Description 245-257
Dynamic loadings, such as earthquakes, blasts, and wind, may be unanticipated for a bridge during its design phase,
which is the essential infrastructure in the transport system. Therefore, wind barriers associated with the bridge deck could
adversely impact the dynamic stability and require to be designed under extreme wind impact. Fortunately, the research said
innovative materials improve performance under high dynamic loads. In the present study, incompressible computational
fluid dynamic has been adopted to explore the aerodynamic and aeroelastic responses of a Trapezoidal box girder bridge
deck section for several materials based solid wind barriers: Normal concrete, crumb rubber concrete, alcofine-based crumb
rubber concrete, silica fume-based crumb rubber concrete and glass fibre-reinforced polymer concrete. The improved
material features help to use innovative, sustainable alcofine-based crumb rubber concrete as a catalyst in solid wind
barriers. The bridge deck does not exhibit any significant changes in aerodynamic characteristics. Under turbulent wind, the
wind barrier on the deck section is more resilient to the vortex. The shear layers separate from the wind barrier's top,
influencing the torsional moment and the bridge deck dynamics. Finally, alcofine-based crumb rubber concrete improves the
wind resistance capacity of the wind barrier.
