| dc.description.abstract | 本研究針對具不同挫屈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，由研究結果得知，隅撐抗彎構架中，若加大隅撐尺度則其強度、勁度均將提高，然若隅撐挫屈強度過大則結構強度將由梁構件之破壞控制，因此強度過大之隅撐配置，對於結構耐震性能之提升並無助益。實驗結果亦發現，隅撐挫屈之發生位移比與構架行為有關，若其過早發生，則結構強度及勁度之提升有限；隅撐鋼結構之耐震性能與其隅撐配置方向及尺度有關，在相同切削長度下有效斷面積愈大其消能行為愈佳，另就隅撐構架之設計而言，配置面內挫屈隅撐，應為一較佳之選擇。

| dc.description.abstract | This study focused on the experimental evaluation of the knee-braced moment resisting frames (KBRFs). A series of cyclic loading tests were conducted on the special moment resisting frame (SMRF) and KBRF frames with knee braces applied in the in-plane and out-of-plane buckling directions. It was found from the tests that the structural stiffness of KBRFs increased when knee braces with larger dimensions were used. It was also found from the comparisons that the strength of the knee-braced frames was significantly enhanced no matter the knee braces buckled in the in-place or out-of-plane direction. However, the drift at which the knee brace members reached the buckling stage was higher for KBRF frames with braces installed in the in-plane buckling direction. This phenomenon led to higher energy dissipation that is essential to the effective seismic design of structures. Therefore, it is suggested that braces with in-plane buckling pattern be adopted in the seismic designs of KBRF frame structures.
