Abstract
In order to investigate ways of reducing vibrations of building structures subjected to excitation acting on intermediate storey, active vibration con trols are conducted with active control devices installed on different floo rs of the structure, and the effective location of control devices is also investigated. In this paper, we propose a new 'Discrete-Optimizing Control Method' for vibration control. The control forces are determined analytical ly which makes the 'discrete-index function' minimum. Through numerical sim ulation, the Discrete-Optimizing Control Method is proved to be an effectiv e control method. The response reduction effects are the best when the cont rol devices are concentrated on the adjacent three floors of the vibration source, Copyright (C) 2000 John Wiley & Sons, Ltd.
