为研究钢骨超高强混凝土柱的抗震性能，对6根钢骨超高强混凝土柱（λ＝2．6）在低周反复荷载下进行试验，并且分析了试件的破坏过程和破坏方式，以及轴压比、配箍率及型钢形式对延性的影响。试验结果表明：钢骨超高强混凝土柱主要破坏形态为弯曲破坏和弯剪破坏，发生弯曲破坏的试件荷载-位移滞回曲线饱满，下降段较为平缓，表现出良好的抗震性能，发生弯剪破坏的试件荷载-位移滞回曲线狭窄，下降迅速，抗震性能较差；配箍率高、轴压比小、配置 H 型钢试件抗震性能好。
為研究鋼骨超高彊混凝土柱的抗震性能，對6根鋼骨超高彊混凝土柱（λ＝2．6）在低週反複荷載下進行試驗，併且分析瞭試件的破壞過程和破壞方式，以及軸壓比、配箍率及型鋼形式對延性的影響。試驗結果錶明：鋼骨超高彊混凝土柱主要破壞形態為彎麯破壞和彎剪破壞，髮生彎麯破壞的試件荷載-位移滯迴麯線飽滿，下降段較為平緩，錶現齣良好的抗震性能，髮生彎剪破壞的試件荷載-位移滯迴麯線狹窄，下降迅速，抗震性能較差；配箍率高、軸壓比小、配置 H 型鋼試件抗震性能好。

To study the seismic performance of steel-reinforced ultra-high-strength concrete columns ,the test research of 6 steel-reinforced ultra-high-strength concrete columns (λ = 2 .6) subjected to low-cyclic repetitional loads was carried out .Then ,the specimens’ failure process and modes as well as the effects of the axial compression ratio ,reinforcement ratio and section steel shape on the ductility of the steel-reinforced ultra-high-strength concrete columns were discussed . The experimental results show that the main failure patterns of the specimens are bending failure and shear failure .The hysteretic curves of bending failure specimens are plump with relatively slow descending branches ,showing excellent seis-mic behavior .However ,the hysteretic curves of shear failure specimens are slim with relatively quick descending branch -es ,showing bad seismic behavior .The specimens with the high reinforcement ratio ,high axial compression ratio and H-shaped section steel show excellent seismic behavior .
