利用摩擦機制來消散能量為一相當簡單的力學概念，惟受限於早期金屬材料之摩擦係數過低，致使摩擦阻尼器之耐震容量較低，難以滿足工程實務上的需求，嚴重限制其於工程應用上的發展。為彌補摩擦材料之摩擦係數過低的缺憾，本研究提出以特殊合金材料為核心之摩擦阻尼器。經元件測試結果顯示，以特殊合金為核心設計之摩擦阻尼器具有相當穩定且飽滿的遲滯迴圈，其力學行為與庫侖摩擦機制相符，且與擾動頻率（速度）無關，特性容易掌握。此外，特殊合金所具有之高摩擦係數（μ>0.7），遠高於習用之摩擦阻尼器，可大幅增加阻尼器之設計容量。本研究進一步將摩擦阻尼器與H型鋼組成適用於結構抗風制震之摩擦阻尼斜撐，並經一系列地震模擬振動台之測試。試驗結果顯示，加裝摩擦阻尼斜撐可顯著降低各樓層之加速度反應，證明韌性斜撐優越之防震性能。結構加裝摩擦阻尼器作為消能元件，因摩擦機制使整體結構成為高度非線性系統，本研究根據剪力平衡概念，求解結構系統之非線性動力反應。數值模擬結果顯示，結構加裝摩擦阻尼器確實可以有效降低結構的受震反應。

Applying friction mechanism for energy dissipation has become a considerably simple and elegant mechanical concept. Its only restraint lies at the rather low friction coefficient in metal material of the earlier stage and results with the low capacity for earthquake-resistance. And this severely hampers the capability to satisfy engineering practical needs as well as its engineering application potential. In order to compensate the rather low friction coefficient from the materials, this research proposes a special alloy material as the core for friction damper. After going through element tests, the findings indicate that this friction damper with its core made of special alloy has relatively stable, rich and full hysteresis loop and its rate-independent stable and rich hysteresis loops with characteristics of the Coulomb's friction mechanism. Other than these, the special metal alloy has high friction coefficient (μ>0.7) far exceeding those of the commonly used friction dampers, thus it can greatly increase the design capacity for friction damper. This research will further apply the combination from friction damper and H-beam to adapt to frictional damping brace and have it undergo a series of seismic performance tests. And test findings reveal that with added friction damper bracing, it can lower the acceleration response at each floor level. While the structure is installed with friction damper for energy dissipation element therefore the friction mechanism can render the overall structure into system of the highly nonlinear ones, therefore this research can then base upon the shear balance method to proceed to seek the solution for nonlinear dynamic responses from the structure system. And the numerical simulation findings support that structure with added friction damper can really lower the effective seismic response.
