| dc.description.abstract | 本研究針對變厚度X形剪力鋼鈑消能裝置進行初步的分析與試驗。首先利用有限元素軟體分析比較幾種不同尺寸比例的鋼鈑承受剪力變形及消能的情形；接著探討本研究所採用之變厚度X形消能鋼鈑與日本蜂巢式等厚度X形消能鋼鈑之間的差異，並以實驗驗證分析預測的準確性；最後提出應用在消能設計上的初步建議。
實驗驗證用之試體，共分為三個系列、十七組變厚度X形鋼鈑消能裝置。各系列試體有著不同的消能鋼鈑配置，且各試體消能鋼鈑尺寸不一，但其高寬比及厚度比均控制一樣。由實驗結果顯示：圓管包覆型消能裝置有較佳的受剪穩定性，且其消能行為接近分析預測值。本研究亦利用兩組試體實驗結果，提供一條疲勞壽命曲線，以供耐震設計者參考。 | zh_TW |
| dc.description.abstract | This study is aimed at the preliminary analysis and experiment for the x-shaped dampers with non-uniform steel plate thickness. At first, several steel plates with different aspect ratios for the comparisons of shear deformation and energy dissipation are analyzed by means of FEM. Then, the x-shaped damper with non-uniform steel plate thickness adopted in this study compares with the honey-comb dampers in energy dissipation. Besides, experimental study is performed to observe the merit of the energy dissipation devices. Finally, some design suggestions are proposed.
Three kinds of specimens, totally seventeen, are tested. Each type of specimen has different layout for energy dissipation. The specimen dimensions are different from each other, but the aspect ratios for the specimens are kept all the same. The test results show that the shear steel plates connected inside the circular tubes have more stable energy dissipation. The test results also match well with the analytical predictions. In addition, a fatigue life curve related to the seismic design is provided from two test results. | en_US |
