摘要

本研究分析與探討鋼結構系統加裝高效能阻尼機構對減震效益之探討。探討鋼結構系統加裝高效能阻尼機構用其於結構之減震控制，作為新建、補強及修復等結構工程之消能元件。以提高結構耐震上的效果，並能提昇新建、補強及修復等結構之耐震能力，將鋼結構在地震力作用下之振動量大幅降低至可容許之範圍內，以確保人與鋼結構之安全，進而減緩地震所造成之災害。
近年來，國際間發生許多震撼人心之大規模地震災害，造成人民生命財產嚴重損失，結構破壞崩塌，且造成人心恐慌。而由於這些地震災害的發生頻傳，使得地震頻繁的國家，如美國、日本及台灣都必須投入大量的人力與物力以求耐震技術之研發與落實。
由921地震可知眾多結構物於地震災害中，遭受地震嚴重損壞
鋼結構系統是重要也常見的建築結構，則必須保持其結構之穩定性，因此利用前人所研發之高效能阻尼機構，在不改變鋼結構系統本身之自然振動頻率、且不改變鋼結構系統之勁度情形下，加裝高效能阻尼機構於鋼結構系統來探討其減震效益。鋼結構系統加裝高效能阻尼機構，在不改變結構之自然振動頻率、勁度下，但卻能增加鋼結構的抗震效果，減少地震對鋼結構所造成的破壞。欲不改變原結構系統之自然頻率下裝置高效能阻尼機構於原鋼結構系統中。本研究是利用有限元素軟體(SAP2000)來進行分析，針對鋼結構系統加裝高效能阻尼機構進行減震之效益分析。

This study analyzes and systems installation of Steel efficient mechanism to investigate the effectiveness of the shock absorber damping energy. The installation of high-performance steel structural system damping energy dissipation element structural engineering of its control mechanism used in damping structures, as new construction, repair and reinforcement. To improve the seismic effects on the structure, and can enhance the new, reinforcing and repair capability seismic structure of the steel in the amount of vibration under earthquake force significantly reduced to within the range of allowable to ensure the safety of people and Steel thus slowing the disaster caused by the earthquake.
In recent years, many large-scale earthquake disaster stirring among nations, resulting in heavy losses of life and property, destruction of structure collapse and cause people to panic. And because of the frequent occurrence of these earthquakes, earthquake-prone countries such as the United States, Japan and Taiwan have to invest a lot of manpower and material resources in order to develop and implement technology of shock.
By the 921 earthquake found numerous structures in earthquake disaster, suffered severe earthquake damage
Steel systems are important and common structures, it must maintain the stability of the structure, so the use of high-performance damping mechanism developed by their predecessors, the steel structure without changing the system itself, the natural vibration frequency without changing the system of steel stiffness under the circumstances, the installation of high-performance damping mechanism in steel damping system to explore its benefits. Steel installation of high-performance system damping mechanism, without changing the natural vibration frequency, the stiffness of the structure down, but it can increase the effect of seismic steel structures, steel structures reduce the damage caused by the earthquake. For high-performance devices without changing the natural frequency of the damper mechanism under the original structure of the original systems Steel systems. This study is the use of finite element software (SAP2000) for analysis, the installation of high-performance damping mechanism damping of the cost-effectiveness analysis of the steel structure system.
