Description
Wanbo An, Fuyou Xu, and Miaomin Wang model a trick to calm bridge sway in a 2025 study. Flat plates hung under water from cables beneath a bridge can add damping, the force that eats sway. Such plates could be fitted for a short time when flutter, a wind-driven shake, threatens a long span.
Their model joins a stiff deck, square plates, and the cables that hold them. Tests on a small deck in the lab backed the math. Plate size, mass, and cable stiffness each changed how well the deck's twist was damped. The team derived plain formulas for the best mass and the peak cable pull.
