These seismic vibration control systems are connected using braces in series and installed with pins to the building structure, enabling installation with little impact on the building structure. This book details testing, analysis and case studies of dampers at braced positions and also exposed to small amplitude vibration.

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).
