| dc.description.abstract | 由於近斷層地震通常具有較長週期的脈衝震波，對結構物之危害往往比同規模遠域地震大，尤其近十年來國內外幾個知名大地震發生後，近斷層效應影響更是受到重視，故本研究針對具摩擦及挫屈控制機制之Y型隅撐構架，搭配不同尺寸之切削鋼板做為消能裝置，分別使用近斷層歷時進行實驗，以界定其在近斷層耐震設計之應用性及可行性，並比較其與一般地震加載歷時之結構行為。
由隅撐構架結果實驗結果得知，Y型隅撐構架於近斷層初始之衝擊下，仍可使整體構架於1.8%之內皆保持彈性階段。此外，若搭配適當之消能隅撐，可於消能構件挫屈前，降低梁柱接頭受力，有效延後梁端降伏情形。而整體構架總能量消散方面，仍可保有傳統抗彎構架之1.4~1.6倍，初始構架勁度也較抗彎構架高約4.2倍，顯示此設計於一般地震加載或近斷層加載歷時，皆可有效發揮其效益。對於結構設計，具有相當之可行性。 | zh_TW |
| dc.description.abstract | Near-Fault earthquakes possess long-period pulse and momentary input energy, thus usually causing severe damage to structures. This study is focused on the performance evaluation of the Y-Shaped knee braced frames with various friction and buckling mechanisms. Responses of framed structures under SAC Near-Fault protocol were compared with those of frames subject to SAC loading protocol to validate the effectiveness of the proposed Y-braced frame designs.
According to the experimental results, the Y-braced frames could maintain the elastic stage within 1.8% drift ratio under the initial impact of the Near-Fault. It is also shown that the force of the beam-column joints was effectively reduced and the occurrence of plastic hinges was also delayed. Comparisons of test results validated the applicability of Y-braced frames to the seismic designs. | en_US |
