    Abstract: 本研究針對應用斜拉鋼筋於高強度中空複合構材之行為,進行一系列實驗研究探討,藉由16根配置不同斜拉鋼筋試體承受純扭矩以及固定軸力與不同組合反覆載重之試驗,探討斜拉鋼筋對構件極限強度、破壞模式、韌性容量、勁度衰減與能量消散行為之影響。研究結果顯示,含斜拉鋼筋之構件在偏心載重作用下,其勁度高於未加斜拉鋼筋之構件,適當配置斜拉鋼筋構件之強度、韌性以及能量消散能力均較未配置者為佳,斜拉鋼筋不僅對構材核心混凝土圍束效果有相當之助益,其對構材之扭轉撓曲效能亦可有效提昇,上述結果顯示,應用斜拉鋼筋於中空複合構材設計,具有相當之可行性。 This study focuses on the torsional behavior of hollow composite members composed of encased steel tubes and high-strength reinforced concrete with inclined bars. A series tests of different composite section disposition with inclined bars subjected to different combination cyclic loadings, research the behavior of the inclined bars to the member’s ultimate strength, failure pattern, ductility , stiffness reduction and energy dissipation. Test results showed that the stiffness of members with inclined bars were significantly increased when subjected to torsion and combined loading coupled with torsion, the suitable design inclined bars make member’s strength , ductility and energy dissipation better.
