    Abstract: 鋼骨鋼筋混凝土結構,兼具鋼筋混凝土及鋼結構之優點,為一 良好耐震構材,但其斷面配置與韌性關係至今仍少有相關研究。一般 認為鋼骨可增加構件之韌性,而鋼筋可增加強度,但在鋼骨鋼筋混凝 土中二者又是該如何配置方為一良好設計,唯一值得探討課題。 本研究利用混凝土強度、鋼骨量、鋼筋量及圍束型式之改變, 探討構件含鋼量的改變在不同混凝土強度及圍束型式下,對構件之位 移、能量韌性及勁度衰減等影響,並使用程式Response 2000 預測構 件彎矩-曲率關係,並分析比較之。研究顯示,在一般強度混凝土中 以鋼骨量的改變對構件韌性有較大改善,而在高強度混凝土中,無論 鋼骨改變或者鋼筋改變均對構件韌性無明顯改變,但以圍束之型式對 高強度混凝土構件韌性之改善有較顯著效果。 Steel reinforced concrete (SRC) members are suitable structural forms for earthquake-resistant designs because they possess significant strength and ductility. Current studies on the seismic behavior of SRC members are mostly focused on their flexural as well as beam-column responses. Investigation on the relationship between member performance and the section placement is still limited. It has been found in concrete and steel related studies that steel ratio contributes to the ductility enhancement and the steel reinforcement helps increase member stiffness. Since the SRC members are composed of steel and reinforced concrete, the placements of steel and steel reinforcement also affect the members’ behavior. This study is focused on the experimental investigation of seismic performance of SRC members composed of normal and high strength concrete with various reinforcement placements. Test results show that the ductility of normal strength SRC members is governed by the steel ratio. It is also confirmed that the ductility of high strength SRC members is affected by the effectiveness of confinement.
