液流阻尼器可有效提高結構之阻尼比，達到減震效果，然而一般建築結構基於使用性，均會提供相當勁度以限制其層間位移量，而導致阻尼器位移量降低，使得消能效果大打折扣。為達提高消能之目的，遂有菱形機構及六角形機構阻尼系統的提出，藉由其幾何變形放大阻尼器之位移，達到提高阻尼器消能之目的。論文中利用SAP2000N軟體進行數值模擬分析，在地震力作用下以諸多分析實例，證實六角形機構阻尼系統確實能有效放大位移量，達到消能減震之功能，並以自由振動法辨識阻尼比確認其修正阻尼器設計公式接近設計所需。

Fluid dampers have been considered to be an efficient device on aseismatic engineering to increase structural damping ratio and so as to reduce the seismic responses. However, in general, inherent stiffness of the structures restrict the structural displacement in relatively small range. That is why the energy dissipation function deducted greatly. Rhombus and hexagon mechanism damper systems are proposed to enlarge the displacement subjected to the damper. Turns out the energy dissipation efficiency can be magnified to fulfill the aseismic engineering purposes. By means of numerical analysis with SAP2000N software package, various cases with the hexagon mechanism damper system installed in different types are analysed to simulate the structures subjected to excitations. It is found that hexagon mechanism can really enlarge the displacement of dampers and reduce the seismic responses to reach the goal of aseismatic structural control purpose. Furthermore, we identify the damping ratio by free vibration method to confirm the value of the correction damper formula.
