“…The response of the bridges to turbulent winds was also simulated numerically (Stoyanoff 2001). Figure 14 shows an example of lateral and vertical deflections measured and numerically simulated for the middle of the main span of the existing bridge upwind.…”

“…Applying buffeting theory (Irwin 1977, Stoyanoff 2001, the same responses were calculated at the design speed. For the downwind position, the corresponding static force and moment coefficients measured in the wind tunnel were applied (see figure 5) with the same wind speed and turbulence properties as used for the bridge in upwind position.…”

“…Buffeting analysis in the time domain was also carried out (Stoyanoff 2001) in which, as shown above, the time histories of responses were numerically simulated. Static force and moment coefficients measured from the sectional model were used for the derivation of the design wind loads.…”

Wind engineering investigation of the Parallel Tacoma Bridges was performed. Half a century after the historic collapse of the original Tacoma Narrows Bridge, aerodynamic instability was again the principal concern. Since it was proposed to build a new parallel bridge only 61 m from the existing bridge, aerodynamic interference effects between the two structures were carefully examined. Initially the local wind climate and the bridges' wind exposure were examined. Sectional models and full aeroelastic models of both bridges were constructed and tested to evaluate aerodynamic stability and wind loading. In addition, full-scale measurements were undertaken on the existing Tacoma Bridge for identification of the natural frequencies of the lowest lateral, vertical, and torsional modes. The study program established that both bridges would be aerodynamically stable and provided detailed wind load distributions for structural design.

“…The quasi-steady theory with regard to slender objects was considered in different ways by many authors [5,6,7,8,9], so it must be pointed out that many different forms of equations determining three components of wind action were created. They may slightly vary from these presented above.…”

“…In this case quasi-steady model can be used to determine dynamic wind action on slender structures [5,6,7,8,9]. This model simplifies wind behavior, however it takes into account aerodynamic turbulence (buffeting) as well as feedback between vibrating building and wind.…”

Abstract. This paper concerns analysis of turbulent wind action on a single-span footbridge. Firstly, the issue of the velocity wind field in the boundary layer was mentioned. Then the simplified quasi-steady model of the wind action on a slender object was presented. Procedure of simulation of turbulent wind action was also shown. The specific case without aerodynamic feedback was considered on the exemplary footbridge. Analysis of such action in numerical program was shown as well as the evaluation of its results.

Connecting infrastructures such as steel bridges are important for sustainable and economic development of society. Understanding the risks to these infrastructures associated with wind is crucial to ensure their resilience, particularly with the evident threat of climate change. The authors will discuss the benefits of early‐stage consulting in delivering climate aware performance‐based design for steel bridges.A holistic approach comprising bridge monitoring, aerodynamic consultation coupled with wind tunnel testing and numerical simulations enables us to understand the structural response of bridges, from an aerodynamic perspective. By combining this knowledge with a local climate model, the bridge response to current and future expected wind conditions, can be predicted and assessed.The outcomes of such an approach enable us to refine design wind loads optimizing material usage and ensuring safe and cost‐effective construction processes, thereby reducing embodied carbon.
