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.

Altay Okyay is currently the chief executive officer of the RWTH Aachen University research center, CWE-Center for Wind and Earthquake Engineering. He is also the senior engineer of the Chair of Structural Analysis and Dynamics (LBB-Lehrstuhl für Baustatik und Baudynamik) in the Faculty of Civil Engineering at RWTH. Dr. Altay completed his diploma studies at the RWTH Aachen University and written his thesis in LBB researching the earthquake performance and structural control of highway bridges. After graduating from RWTH Aachen University in 2007, Dr. Altay started his carrier in a civil engineering research company in Vienna in the field of vibration control. There, he developed and developed damping systems for buildings, railway bridges and footbridges. During a research project, he also applied a tuned liquid column damper system for ropeway cars. In 2010, he returned to Aachen and started his academic carrier as a research assistant in LBB. In 2013, Dr. Altay finished his doctoral studies with distinction developing a semi-active tuned liquid column damper (S-TLCD), which is patented by RWTH.
His current research interests include semi-active and active damping systems, and structural damping applications using smart materials, such as shape memory alloys and piezoelectric ceramic materials. He is lecturing at RWTH undergraduate and graduate students “Structural Dynamics”, “Structural Control and Health Monitoring” and “Dynamics”, and supervising dissertations in these fields.
