Abstract
This paper shows the active control of nonlinear vibration in cable st ayed bridges using a tendon mechanism and investigates the effect of n eglecting high order modes in the design of the control law on the con trolled response. The paper finds out that many vibrational modes shou ld be considered in the design of the velocity feedback control law, i n order to obtain a stable and damped controlled response as designed.
