Braced Oil Dampers for Buildings


Book Description

The high damping force of oil damper vibration control systems in buildings offers relative safety during earthquakes and at a low environmental cost. The oil damper is connected using braces in series and is installed with pins to the building structure, which minimizes the impact on the building structure and allows installation and removal with ease. This is the first book detailing experimental work and cases of the use of oil dampers in buildings. It shows their effectiveness by detailing the testing and analysis of buildings with them placed at braced positions, exposed to small amplitude vibration, and without them. • The only comprehensive presentation of oil damper vibration control • Covers analysis and design, with case studies and details of testing and experimental results The book is organized systematically to suit students and junior professionals in structural design as well as more specialist engineers. An additional Python code sample is available online for learning the behaviors of oil dampers (Jupyter Notebook environment required). Osamu Takahashi is a professor at Tokyo University of Science, founder of Science Kozo Inc., and an advisor to the New International Structural Design & Engineering Challenge Association, in Japan. Atsuki Yokoyama works in the Research and Development Department of Sanwa Tekki Corporation and has a PhD in Engineering from Tokyo University of Science.

Passive Vibration Control of Structures


Book Description

Research in vibration response control deals not only with prevention of catastrophic failures of structures during natural or accidental/manmade hazards but also ensures the comfort of occupants through serviceability. Therefore, the focus of this book is on the theory of dynamic response control of structures by using different kinds of passive vibration control devices. The strategies used for controlling displacement, velocity, and acceleration response of structures such as buildings, bridges, and liquid storage tanks under the action of dynamic loads emanating from earthquake, wind, wave, and so forth are detailed. The book: Explains fundamentals of vibration response control devices and their practical applications in response mitigation of structures exposed to earthquake, wind, and wave loading Offers a comprehensive overview of each passive damper, its functioning, and mathematical modeling in a dynamical system Covers practical aspects of employing the passive control devices to some of the benchmark problems that are developed from existing buildings and bridges in different countries worldwide Includes MATLAB® codes for determining the dynamic response of single degree of freedom (SDOF) and multi-degree of freedom (MDOF) systems along with computational models of the passive control devices This book is aimed at senior undergraduate students, graduate students, and researchers in civil, earthquake, aerospace, automotive, mechanical engineering, engineering dynamics, and vibration control, including structural engineers, architects, designers, manufacturers, and other professionals.







Design Optimization of Active and Passive Structural Control Systems


Book Description

A typical engineering task during the development of any system is, among others, to improve its performance in terms of cost and response. Improvements can be achieved either by simply using design rules based on the experience or in an automated way by using optimization methods that lead to optimum designs. Design Optimization of Active and Passive Structural Control Systems includes Earthquake Engineering and Tuned Mass Damper research topics into a volume taking advantage of the connecting link between them, which is optimization. This is a publication addressing the design optimization of active and passive control systems. This title is perfect for engineers, professionals, professors, and students alike, providing cutting edge research and applications.




Improving the Earthquake Resilience of Buildings


Book Description

Engineers are always interested in the worst-case scenario. One of the most important and challenging missions of structural engineers may be to narrow the range of unexpected incidents in building structural design. Redundancy, robustness and resilience play an important role in such circumstances. Improving the Earthquake Resilience of Buildings: The worst case approach discusses the importance of worst-scenario approach for improved earthquake resilience of buildings and nuclear reactor facilities. Improving the Earthquake Resilience of Buildings: The worst case approach consists of two parts. The first part deals with the characterization and modeling of worst or critical ground motions on inelastic structures and the related worst-case scenario in the structural design of ordinary simple building structures. The second part of the book focuses on investigating the worst-case scenario for passively controlled and base-isolated buildings. This allows for detailed consideration of a range of topics including: A consideration of damage of building structures in the critical excitation method for improved building-earthquake resilience, A consideration of uncertainties of structural parameters in structural control and base-isolation for improved building-earthquake resilience, and New insights in structural design of super high-rise buildings under long-period ground motions. Improving the Earthquake Resilience of Buildings: The worst case approach is a valuable resource for researchers and engineers interested in learning and applying the worst-case scenario approach in the seismic-resistant design for more resilient structures.
