在橋樑消能技術發展上，近年來阻尼裝置已被考慮當成消能元件，不但可以有效消散地震輸入橋樑的能量，也可以減少橋樑在地震下的位移反應。本研究將先針對三角形加勁阻尼裝置來進行試驗和理論分析。再利用有限元素法來分析三角形加勁阻尼器，進而和理論解來比較，結果發現三角形加勁阻尼器顯示能提供穩定強大的消能作用。另外本文也針對三角形加勁阻尼器的遲滯迴圈消能的模擬進行研究。利用Wen於1976年所提出的一套力與位移關係的遲滯迴圈模式，將其應用在三角形鋼鈑的遲滯迴圈模擬上。本研究將近一步探討三角形加勁阻尼器的減震效能，對加裝三角形加勁阻尼器的二維平面單間剛架以及三維橋樑進行分析，並且和沒有加裝阻尼器及加裝斜撐的情況進行比較，結果發現加裝三角形加勁阻尼器的情況比沒有加裝三角形加勁阻尼器的情形具有較好的減震效果，但相較於加裝斜撐的情況其減震效果並沒有明顯的增加。

　　For bridge structures, dampers have been considered to be a vibration reduction device, which decreases the structural displacement under earthquakes. In this study, the Triangular Plate Added Damping and Stiffness device (TPADS) is investigated for
bridges. First, laboratory experiments and theoretical solution are used to examine the structural behavior of TPADS. Then, the three-dimensional finite element analysis of a single triangular plate is investigated to compare with the theoretical solution in a good agreement. Both numerical and theoretical results indicate that a single triangular plate of the TPADS can consume significant energy due to cyclic loads. Moreover, the hysteretic stress-strain relationship is generated obviously. To analyze the whole structure with the TPADS, a sub-program of the TPADS element is developed in the nonlinear finite element program (AN), and the hysteretic loop developed by Wen is used in this element. Afterward, this program is used to analyze two-dimensional frames and three-dimensional bridges. Finite element results show that the TPADS can reduce vibration for structures under earthquakes; however, compared with the installation of braces, the reduction of structural displacements due to TPADS is often not so efficient.
