本研究針對具特殊自復位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，自復位隅撐抗彎構架中，若加大預力桿件尺度則其強度、勁度均將提高，實驗結果亦發現，加長預力桿件長度則其保留自復位能力之位移將提升，然若隅撐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。 This study focused on the experimental evaluation of seismic performance of knee-braced moment resisting frames with self-centering braces. A series of cyclic loading tests were conducted on the special moment resisting frame and self-centering knee-braced frames. It was observed from the tests that the self-centering capability of the structures was effectively sustained when the self-centering braces remained functional. It was also found from the test results that the structural stiffness of the self-centering structure was increased when post-tension bars with larger cross-sectional areas were adopted. Comparisons on the test results indicated that higher self-centering capability of structures could be expected when longer post-tension bars were used.
