摘要

本研究目的在改良U形鋼板斜撐之組裝方式，並驗證含U形鋼板之斜撐具有優異之消能能力、耐疲勞壽命與穩定性，並與理論公式比較。研究結果顯示，改良U形鋼板斜撐之組裝方式後，能提高斜撐之勁度與消能能力，且能保有飽滿與穩定之遲滯迴圈，組裝方式因摩擦力的介入而具有正面之效果。疲勞試驗證明抗疲勞能力，與U形月之曲率半裡有關，試驗之最大軸力較Kelly所建議之公式推估值大。

The objective of this paper is to improve assembled of bracing with U-shaped steel plates, and prove that the bracing with U-shaped steel plates exhibit energy dissipation, fatigue resistance and stability. The following results are obtained: (1) after improve assembled of bracing with U-shaped steel plates, it can be increase the axial stiffness, energy dissipation, and excellent hysteretic loop. (2) For this assembled induce a friction, which can he increase dissipating energy. (3) Fatigue test result that a fatigue resistance depends on curvature of U-shape steel plates. (4) The maximum axial load from present test is higher than that from suggested by Kelly.
