碩士 === 國立臺灣大學 === 機械工程學研究所 === 95 === This thesis discusses the application of a new mechanical element, called Inerter, to building suspension control. The Inerter was proposed as a real two-terminal mechanical element, which is a substitute for the mass element, with the applied force proportional to the relative acceleration across two terminals. Ideal Inerter have been applied to vehicle, motorcycle and train suspension control, where significant performance improvement was noticed. In this thesis, idea Inerter are adopted to explore the application to building suspension control with traditional suspension systems. To investigate the performance benefits of building suspension with Inerter, three building models - rigid body Building model, flexible column model, and portal frame model - were proposed to analyze the performance using selected performance indices. Finally, we apply the ideas to a real building model – Shin Ji building. From the simulation results, Inerter were deemed effective in reducing vibrations from earthquakes and traffic.
