| dc.description.abstract | 本研究針對具有曲線消能器之 A 型隅撐構架耐震性能進行探討，
研究中針對不同尺寸曲線消能器以及應用此消能器之隅撐構架分別
進行試驗以確認其應用性。
另外由曲線消能器之構件試驗結果得知曲線消能器在小位移比
0.38%至 0.56%之間，即進入塑性階段，由此開始消散能量，且在位
移比 7%之內皆不會發生破裂，顯示曲線消能器具有極佳韌性。
且另外由 A 型隅撐構架試驗結果得知，A 型隅撐構架具有適當之
位移放大機制，可有效利用曲線消能器消散能量，此外隅撐系統亦可
降低梁柱接頭之受力，延後梁端降伏之狀況。而構架初始勁度較抗彎
構架高約於 3.77 倍，且消能能力提升為 1.42 至 2.00 倍。由上述結果
可知，A 型隅撐構架可有效提升構架之承載性能。

| dc.description.abstract | This study focused on the performance evaluation of A-knee braced
frame. The purpose of this research is to confirm the applicability of A
knee brace to the framed structural design
According to the experimental results, curved damper started to
dissipate energy in early deformation stage and had exhibited ductility to
7% deformation ratio without crack. Experimental results of A-knee braced
frame tests show that deformation ratio of curved damper could be
amplified in the proposed A-knee brace design. Therefore, significant
contribution of energy dissipation from curved damper was validated.
Further comparisons showed that the initial effective stiffness of A-knee
braced frame was 3.77 times of that of the moment resisting frame. The
energy dissipation of the proposed A-knee braced frame was also increased
by 1.42 to 2.00 times. The significant performance improvements validated
the applicability of A-knee braced frame design.
