ST-91-24  aA thesis submitted in partial fulfillment of the requirements  for the degree of Master of Engineering, School of Engineering and Technology  aThesis (M.Eng.) - Asian Institute of Technology, 1991  aThe active wave control is studied theoretically for the  application to wind-induced cable vibration in cable-stayed bridges .  The control energy, the maximum control energy rate and t he maximum  strain energy are compared in order to evaluate the control performance  for free vibration. It is found that the control performance depends on  the actuator location and the mode shape .  The control performance for the excitation is discussed. The  effectiveness of the control for the forced vibration is shown . One of  the passive controllers, the oil damper is compared. The active wave  control presents better performance than the oil damper. The efficiency  of the control for the self-excited vibration i s also shown, although  the wave equation changes and the control law does not hold in the case  of self-excitation.  It is suggested from all the results that the active control is  feasible for cable vibration in cable-stayed bridge. 0aCablesxVibration1 aYamaguchi, Hiroki, eChairperson1 aKarasudhi, Pisidhi, eExamination Committee0 aWorsak Kanok-Nukulchai,eExamination Committee2 aKeidanren Foundation, Japan, eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
