How do they get structures to sway in the wind?

Structures are designed to sway in the wind through specific engineering techniques that enhance flexibility and resilience. This is achieved by incorporating materials and designs that allow for controlled movement, such as using flexible joints, dampers, and tuned mass dampers that absorb and dissipate energy. The structural shape, often aerodynamically optimized, helps reduce wind loads. By allowing movement, these designs prevent structural failure and ensure safety during high winds.
