The present study is concerned mainly with a numerical study on mitigation of structural vibration for structural control applications using TLCD. To achieve this goal, two fluctuating wind loads are first generated by means of wind spectra in both directions, that is, alongwind and acrosswind, and a simple method Is proposed to deal with nonlinear damping of TLCD A controllable passive (semiactive) and proposed active TLCD systems are utilized to overcome the shortcomings of passive system It is found that proposed active system is very effective to reduce the structural vibration in both cases of alongwind and acrosswind without considering the requirement of large control force. On the other hand, semiactive system shows lesser response reduction than the case of active system, while exhibits further reduction in the responses than that of passive system. However, semiactive system has a merit in the control force aspect because it requires relatively small control force to mitigate excessive structural vibration by utilizing controllable valve Finally, new concepts of TLCD system and Installation of multiple-TLCD are proposed to cope with bi-directional and torsional vibrations of structure due to wind/seismic loads
