摘要
[[abstract]]In this study, a shaking-table test was performed to verify a proposed discrete-time modal control method that is suitable for seismic control of structural systems and also easy for digital control implementation. The computation of the feedback gain is formulated in a discrete-time domain and is given in a concise matrix form. A method for generating the best achievable eigenvectors that are most consistent with the target values is also proposed. The test involves a full-scale three-story building model that is actively controlled by an active bracing system. The test results show that the proposed discrete-time modal control can be a very efficient and promising method for mitigating the seismic response of building structures. For the building model tested, the performance of the proposed method with only two feedback signals can be as effective as that of full state feedback control.
