    摘要: 本研究針對不同中空斷面之高強度中空雙鋼管混凝土構件之承載行為進行探討,研究中以一系列組合載重試驗,界定構件空心比與其極限強度、韌性、勁度衰減及能量消散等結構行為之關係。研究結果顯示,在適當之空心比配置下,構件之極限強度與韌性均可優於具相同斷面尺度之鋼管混凝土構件。由試驗結果發現空心比之增加將降低構件之變形能力與其能量消散之能力。實驗結果亦發現,高強度中空雙鋼管混凝土柱之非彈性勁度與其位移比呈自然對數之關係,空心比愈大者,其勁度之衰減速率愈快。本研究中亦由研究結果歸納設計公式,以供中空雙鋼管混凝土構件工程應用之參考。 This study focused on the seismic performance evaluation of high strength sandwich composite members. A series of combined loading tests on members with various sectional compositions were conducted to investigate the relationship between the sections’ void ratios and the members’ strength, stiffness, and ductility. It was found from the test results that the strength and ductility of sandwich members with adequate sectional void ratios were higher than those of concrete-filled tubes with similar dimensions. Test results also showed that the members’ deformation and energy dissipation capacities decreased when the sectional void ratios increased. It was further validated from response comparisons that the members’ stiffness deterioration rates were larger when the members’ sectional void ratios increased. A simplified expression for member stiffness evaluation was proposed for engineering practice references.
