How does aerodynamic affect bridges?

Answer 1

Aerodynamics significantly affects bridges by influencing their structural design and stability, particularly for long-span and cable-stayed or suspension bridges. Wind forces can induce vibrations and resonant frequencies that may lead to structural fatigue or even failure if not properly accounted for. Engineers must consider aerodynamic effects in their designs to mitigate risks such as flutter, oscillations, and wind-induced loading, ensuring the bridge remains safe and functional under various weather conditions. Incorporating aerodynamic features, like streamlined shapes and wind barriers, can enhance performance and longevity.
