| dc.description.abstract | 本研究針對具挫屈控制機制隅撐之多層多跨隅撐抗彎構架進行反覆載重試驗，以界定其耐震性能。由研究結果可知，隅撐構件尺度大小對隅撐抗彎構架影響甚劇，隅撐挫屈強度越大，構架系統之強度、勁度將有所提高，若配置挫屈強度過大之隅撐構件，則構架系統強度將由梁構件之破壞控制，因此適當隅撐挫屈強度配置，方能得到較佳之耐震性能。而隅撐構件發生挫屈時機與構架行為有關，若過早發生挫屈，則對系統之強度及勁度提升將有限。實驗結果亦發現，不同樓層配置隅撐挫屈強度差異較大之隅撐構件於構架中，構架系統於隅撐構件挫屈後，其強度折減率也較高，故加入隅撐構件於多層構架系統中，配置挫屈強度相近之隅撐構件應為較佳之選擇。

| dc.description.abstract | This study focus on the seismic performance through the cyclic loading test of controllable bucking mechanism of multi-layer and multi-span knee brace resisting frame. As shown in the result, the scale of knee braces highly influences its knee bracing frame. The higher strength the buckling of knee braces is,the higher strength and stiffness of frame system increases. If the over-strength buckling of knee braces are deployed, the strength of frame system will be controlled by damage of beam element. Therefore, an appropriate strength of buckling of knee braces should be employed to generate the better seismic performance. However, the timing resulting in occurrence of buckling of knee braces is connected with frame behavior. Provided that the buckling of knee braces occurs earlier, the strength and stiffness of system will be constrained. The finding also indicates that if the wide range of strength scale of buckling is deployed in frame system among different layers, it leads to high discount rate. It is therefore add buckling of knee braces in the multi-layer frame system. Also, the similar strength of buckling of knee brace is preferable in multi-layer frame system.
