Active Control of Structures
With Active Control of Structures, two global pioneerspresent the state-of-the-art in the theory, design and applicationof active vibration control. As the demand for high performancestructural systems increases, so will the demand for informationand innovation in structural vibration control; this book providesan effective treatise of the subject that will meet thisrequirement. The authors introduce active vibration control throughthe use of smart materials and structures, semi-active controldevices and a variety of feedback options; they then discuss topicsincluding methods and devices in civil structures, modal analysis,active control of high-rise buildings and bridge towers, activetendon control of cable structures, and active and semi-activeisolation in mechanical structures.
