1st Edition
Braced Oil Dampers for Buildings Development and Analytical Modeling
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).
