中文摘要
使用有限元素軟體ANSYS Workbench 12版來分析結構物受震時的耐震反應特性，比較加裝與未加裝阻尼器之結構反應。有鑑於以往多數相關論文的研究，都是將結構物假設成剪力屋架且結構物仍在彈性範圍內，然而真實結構物的行為相當之複雜，結構物在受力後其材料行為可在彈性與非彈性之間反覆作用，動力行為非常複雜，本研究即針對此複雜之問題，以有限元素數值分析法，探討一三層樓鋼架結構之彈塑性耐震動力特性。並以等量之阻尼器消能元件，作不同之安裝安排，進行耐震效能之比較。
本論文是針對個別結構模型案例，由分析的結果顯示，加裝阻尼器之結構物均可得到正面的控制效果，原則上於低層加裝阻尼器之耐震效果較為顯著；若改變結構模型，則必須重新進行分析，才能決定何種阻尼器加裝方式可提供更好的控制效果。若考慮到舒適度與安全性，Case 4將會是較佳的選擇。

Abstract
Finite element software package ANSYS Workbench v.12 is used to analyze a three story seisemic fluid damper controlled structure.The story building is not just assummed to be linear shear building system as previously considered.However, it is quite complex problem as material responsed beyond elasticity. Nolinear steel material behaviors are pre-assumed, turns out both of raw structures and fluid dampers are responded into nonlinearly to reveal the responses much realistically.In other words, the problem treated herein is nonlinear dynamic system.The major purpose of the thesis is to investigate the control effects of the structure as limited numbers of energy dissipation fluid damper installed in different combinations to the floors.
This thesis is for individual structure model. Basically, resistance of seismic wave of the building increased as fluid dampers installed at the lowest floor. For different structure models, it has to be re-analyzed to decide which combination is better for the structure. In the presented examples, Case 4 is the one much more suitable for the presented structure models in case comfort and safety are being considered.
