DOI: 10.1126/sciadv.1701512
Abstract: This study develops “crash test dummies” to help designers avoid their footbridges oscillating or bouncing alarmingly. Modern pedestrian and suspension bridges are designed using industry standard packages, yet disastrous resonant vibrations are observed, necessitating multimillion… read more here.
