To study the cyclic behavior of partially precast steel fiber high-strength concrete columns with high-strength steel bars, four full-sized square column specimens were fabricated and tested under constant axial load and horizontal cyclic load. The effects of the strength of precast concrete shell and the diameter of cast-in-place column core were analyzed in detail. The results show that partially precast steel fiber high-strength concrete columns have good seismic performance and deformation ability. Compared to the concrete column with lower strength of precast concrete shell, the concrete column with higher strength of precast concrete shell showed higher bearing capacity and energy dissipation capacity while lower ductility. Moreover, with the increase of the diameter of cast-in-place column core, the bearing capacity and the deformation ability of the specimen decreased. Finally, based on the experimental research and theoretical analysis, a calculation model for predicting the maximum bearing capacity was proposed, and the results obtained from the formulas were in good agreement with those from the experiments.

为了研究部分预制钢纤维高强混凝土柱与高强度钢筋的循环行为，制作了四个全尺寸方柱试样，并在恒定轴向载荷和水平循环载荷下进行了测试。详细分析了预制混凝土壳体的强度和现浇柱芯直径的影响。结果表明，部分预制钢纤维高强混凝土柱具有良好的抗震性能和变形能力。与预制混凝土壳强度较低的混凝土柱相比，预制混凝土壳强度较高的混凝土柱具有较高的承载力和能量耗散能力，而延展性较低。而且，随着现浇柱芯直径的增加，试样的承载力和变形能力下降。最后，在实验研究和理论分析的基础上，提出了最大承载力的计算模型，其计算结果与实验结果吻合良好。
