Damping of cables by a transverse force
WebOther cable damping models have been suggested recently, but have not ventured out of the viscous realm. Kauffman, Lesieutre and Babuska proposed a rotational viscous model that improved upon motion- or strain-based ... did not support a moment or lateral force, so only transverse force was received from the shaker. WebAs an important force transmission member of the cable-stayed bridges, cable has the characteristics of light weight, high transverse flexibility and low intrinsic damping [].It is extremely easy to be excited by the various types of environmental disturbances to happen to different kinds of cable vibrations, such as rain-wind induced vibrations, vortex …
