Braced Oil Dampers for Buildings

Book excerpt: 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).
