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 a 606 $aStructural control (Engineering) 615 0$aStructural control (Engineering) 676 $a624.1/71 700 $aPreumont$b Andre$0342077 701 $aSeto$b Kazuto$01761655 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910876676003321 996 $aActive control of structures$94201240 997 $aUNINA
