摘要:	本研究針對波浪形鋼板消能裝置，以及應用波浪形鋼板消能裝置之具消能隅撐內框架構架分別進行反覆載重實驗，以界定其耐震性能。由實驗結果得知，波浪鋼板消能裝置之非線性行為，受鋼板之水平角度以及厚度影響，且具消能隅撐內框架構架系統，有降低梁柱接頭受力之效果，並可提升抗彎構架之勁度與消能容量。消能裝置與構架系統之力學行為可以雙線性關係模擬，試驗中表現消能構架系統中之具隅撐內框架，皆無明顯損壞，其破壞皆集中於消能裝置上。此外，本研究利用有限元素軟體ABAQUS分析構架之行為，可有效模擬構架系統之勁度、強度與消能容量，具有相當參考價值。 This study focused on the experimental evaluation on the seismic performance of the frame system with corrugated plate dampers (CPD). The CPD device is manufactured by cold-bending thin plates with desired inclined angles. A series of cyclic loading tests on the CPD with various geometries and frame tests with different CPD were conducted. It was found from the tests that the CPD yielded at small deformation. It is suggested from the test results that a CPD with inclined angle between 68 to 78 degrees be adopted when engineering practice is expected. Also, from the results of frame tests, the frame with CPD has higher stiffness and more energy dissipation. Therefore, this kind of frame design can increase the MRF’s stiffness and damping. In addition, this study analyzes the frame structures by finite element software ABAQUS. From the results, ABAQUS can effectively achieve frame’s stiffness, strength and energy dissipation.
