This book begins by describing the Tuned Mass Dampers (TMD) systems to familiarize readers with the basic concepts, followed by a brief review of the state-of-the-art research findings culled from recent studies in the archival literature. In the third chapter, the applicable structural theories are discussed. Next, the authors examine some advanced and applicable optimization techniques, such as the Genetic Algorithm, and related computer algorithms and modeling techniques to help engineers and researchers in performing computer simulations. Examples from the field appear in the last chapter to reinforce the concepts presented. Instilling practical insight into the TMDs, their applications, basic theories, and modeling techniques, the book is ideal for practical engineers, researchers and students of structural engineering.
