Abstract
Wind-rain induced vibrations of a cable-stayed bridge are damped using tuned mass damper(s) ("TMD"). A TMD-damped cable-stayed bridge is comprised of (a) a bridge having at least one span, at least one pylon, and at least one stay cable extending from a point on the pylon to a point on the span and (b) at least one tuned mass damper in damping communication with the stay cable. A TMD-damped stay cable is comprised of (a) a stay cable comprised of a core of at least one longitudinal element or strand within a tube and (b) a tuned mass damper in damping communication with the stay cable. The TMD can be mounted on the stay cable in a low-profile position relative the stay cable and/or at any desired position along the length of the cable. The TMD can be of annular configuration and comprised of a viscoelastic spring system and an outer mass. The outer mass can be formed of two mating sections.
