As the demand for high performance structural systems increases, so will the demand for information and innovation in structural vibration control; this book provides an effective treatise of the subject that will meet this requirement. The authors introduce active vibration control through the use of smart materials and structures, semi-active control devices and a variety of feedback options; they then discuss topics including methods aStructural control (Engineering)Structural control (Engineering)624.1/71Preumont Andre342077Seto Kazuto1761655MiAaPQMiAaPQMiAaPQBOOK9910876676003321Active control of structures4201240UNINA
