The scope of the book is the application of vibration mitigation systems in structural engineering. The intended content includes the theoretical background covering aspects from both structural dynamics and control engineering point of view. Moreover, passive, active and semi-active devices are explained in detail giving mathematical principles, design considerations and application examples. It also contains detailed information about structural monitoring, as an essential part of the active/semi-active systems, and therefore, provide a full overview about passive, active and semi-active systems in the specific context of civil engineering Book presents a comprehensive coverage of the area of vibration control of civil structures subjected to different types of loading while using passive, semi-active, and/or active controls. Presents the theoretical governing equations as well as the associated design guides of various vibration control mitigation approaches. Discusses structural monitoring aspects such as sensor technology, system identification and signal processing topics. Reviews structural control aspects, such as algorithms. Includes solved examples utilizing MATLAB®/SIMULINK®with source codes of the calculation examples and design tool set. This book is aimed at graduate students, professionals, researchers in civil engineering, structural engineering, structural dynamics, health monitoring, vibration control.
