慣質於建築物懸吊系統之應用

Abstract

在本論文中，我們將討論建築物之隔震模型及應用一個新的機械元件-慣質-於建築物之隔震設計，並探討其性能增益。慣質是由機械系統與電子網路系統彼此間的不對稱性中發現的，用以取代機械系統中的質量元件使得機械與電子網路對應更加完美。慣質在汽車、摩托車與火車的懸吊系統上已證實可以提升隔震性能，在本論文中我們將加入慣質於房屋懸吊系統設計，並分別討論對於剛體建築模型、彈性柱建築模型與樑柱構架建築模型之隔震性能，最後我們將針對一個真實的建築物模型－信基大樓，探討慣質之隔震助益。從模擬結果可知，慣質的確可以有效地降低地震與交通引起的震動。

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.
