The first purpose of this study is to analyze vibration control devices and methods which can secure the safety of buildings and reduce human discomfort against excessive vibration caused by lateral loads such as earthquake and wind. The second purpose is to propose practical ways of implementation of them to real building structures. Research on passive vibration control methods and active vibration control methods were carried out simultaneously, As passive vibration control methods, tuned mass damper(TMD) and tuned liquid damper(TLD) were selected and optimal damping variables were derived through the investigation of effects of their dynamic characteristics on the vibration control of structures. More effective vibration control methods in real situation were studied by the experiment and the comparison of their results with analytic results. About active vibration control method, the investigation of existing control algorithms and transmission methods of power were carried out for the purpose of conversion into or development of the algorithm appropriate to building structures. Also, a survey of general problems occurring in the experiments necessary for the verification of the reliability of active vibration control methods were carried out.
