Like airplanes, skyscrapers, dams and other large engineered structures, bridges constantly deform by design and by necessity. All modern bridges, for example, contain expansion joints to ensure that thermal expansion and contraction will not buckle the bridge or tear it apart. Following the wind-induced collapse of Washington’s Tacoma Narrows Bridge in November 1940, structural design engineers have taken considerable care to ensure that wind stresses will not trigger destructive mechanical resonances in suspension bridges.
