Abstract
Wind loads are the most crucial and critical parameters included in the bridge design process. The influence of wind factors on design arises in avoiding problems that lead to both aero-elastic, and mechanical failures such as flutter, vortex-induced vibrations, and critical deformations.
Cable-stayed and suspension bridges are more sensitive to wind load excitations than other Types of bridges. Accurate wind load calculation is critical during the design of those structures. The dynamic influence of simulated wind loads on steel bridges is studied in this paper. Finite element and finite-volume models and computational fluid dynamics, CFD, were utilized using ANSYS Workbench, (CFD is a branch of fluid mechanics used numerically to simulate flow problems) to simulate wind flow around bridge structures. The wind-structure interaction is considered in this study. Time history wind speeds were used to load the bridge. Wind loads at different wind speeds passing through the bridge and bridge deformations were calculated using two-way fluid-structure interaction (TWFSI). The wind pressures at different wind speeds also were extracted. This study facilitates estimating more accurate wind loads on complicated structures, allowing for economic and safe design.
The presence of truss steel bridges is not intense in these researches to the author’s knowledge, despite their penetration in the sector of transportation especially railways. However, the utilization of two-way numerical estimation of deformations due to wind loads is not widely applied in this area of interest.
