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