本研究對新提出之應用消能鋼板及曲線消能器之隅撐鋼結構耐震性能進行試驗並評估，於研究中配置不同尺度之曲線消能器，探討其應用性及各尺寸參數對整體構架承載性能之影響。此設計中，藉由將梁切成三段並以消能鋼板連接方式，將傳統隅撐抗彎構架之最大彎矩處轉移，避免其於梁與隅撐交界處產生塑性鉸，另搭配曲線消能器以提升其耐震性能。 為驗證此設計之可行性，本研究首先針對不同尺寸之曲線消能器進行構件試驗，以得知消能元件之遲滯行為，後以經由適當配置之不同尺度曲線消能器應用於構架中進行一系列載重試驗，其研究結果顯示，此設計能有效維持梁柱構件等主結構之完整性且提升勁度，整體構架強度可提升為1.3至2.7倍，整體構架總能量消散方面相較於未裝設曲線消能器之隅撐構架亦提升為1.3至2.0倍，由上述之研究結果可知，此設計可有效提升結構之承載性能，對於耐震效能提升設計，具有相當之可行性。;This study focused on the performance evaluation and FEM analysis of steel knee braced frames with curved dampers. The purpose of this study is to prevent the formation of plastic hinges on the beam of traditional knee braced frames. Hence, a new design was proposed. In order to validate the effectiveness of the proposed knee braced frames, a series of cyclic loading tests with various damper dimensions were conducted. According to the experimental results, this design could maintain the main structures in elastic stage. Also, the results showed that significant improvement could be achieved by adding steel curved dampers to the knee braced frames. To be more specific, the strength and stiffness of the proposed design were effectively enhanced. Therefore, the applicability of this design was verified through experimental and numerical studies of the test frames.
