摘要

本研究針對全鋼線網圍束中空複合構材之扭轉撓曲行為，進行一系列實驗研究探討，藉由 18 根相同斷面但不同配置之SRC構件進行彎矩、扭矩及彎矩與扭矩組合載重之試驗，藉由實驗之結果，推求適當之SRC構件細部配置，並探討麻面鋼線網對構件極限強度、破壞模式、勁度衰減與能量消散行為之影響。研究結果顯示，設置適當麻面鋼線網之構件在彎矩、扭矩及彎矩與扭矩作用下，其勁度皆高於設置箍筋之構件，麻面鋼線網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，應用麻面鋼線網於中空複合構材設計，具有相當之可行性。

Hollow composite members have been developed for a long time and people usually use stirrup in composite members. Composite members with stirrups are not only time-consuming, but also cost-highly. According to 18 specimen conducted in cyclic loading tests, the results show that all the specimen with WWF can be significantly enhance their stiffness and ability of energy dissipation. Hollow composite members with WWF do not only have good performance, but also save cost.
