摘要(中) 本研究針對傳統之抗彎構架、依AISC 建議接合方式設計之隅撐
抗彎構架，及具不同控制機制隅撐之隅撐抗彎構架進行反覆載重實驗
，以界定其耐震性能，並探討隅撐搭配控制機制之可行性。從研究結
果中可得知，隅撐抗彎構架中，若加大隅撐尺度則強度將提高，然若
隅撐挫屈強度過大致其無法達挫屈階段，則結構強度改由梁構件控制
，因此過大之隅撐配制並無必要。由實驗結果亦發現，隅撐挫屈之發
生位移比亦與構架行為有關，若其過早發生，則結構強度及勁度提升
有限；另隅撐構件之降伏強度則與隅撐挫屈後構架之承載性能有關。
由構架之承載性能之比較中亦得知，配制控制機制隅撐之構架與依
AISC 建議設計接合板之構架相當，故控制機制隅撐應用於隅撐抗彎
構架有其可行性。本研究中亦以有限元素軟體ABAQUS 建立分析實
驗模型，分析結果顯示，隅撐抗彎構架結構行為模擬時，其建議之隅
撐初始變位可為其長度之千分之二。
摘要(英) This study focused on the experimental evaluation of knee-braced
moment resisting frames. A series of cyclic loading tests were conducted
on the special moment resisting frames and knee-braced frames with
various knee brace arrangements. It was found from the tests that the
strength and energy dissipation capacity of the knee-braced frames were
larger than those of the moment resisting frames. Test results also showed
that the structural responses were closely related to the dimensions of the
knee braces. For knee-braced frames with excessive brace strength, the
failure patterns of structures were governed by the lateral-buckling of the
beams. This incurred major damage in the structural components that was
inadequate in effective structural designs. Comparisons on the hysteretic
behavior between the results from experiments and from ABAQUS
simulations indicated that good correlation could be achieved when an
initial imperfection of 2/1000 of knee brace length was considered.
