摘要

摘要: 为提高钢管混凝土柱轴压承载力，在自密实混凝土中掺入钢纤维，研究不同钢纤维掺量对自密实钢管混凝土柱轴压力学性能的影响。通过设计正交试验，研究3组钢纤维掺量对自密实混凝土强度的影响，并为钢管混凝土钢纤维用量提供依据；对钢纤维组、普通组自密实钢管混凝土柱进行轴压试验，研究钢纤维对自密实钢管混凝土柱轴压力学性能影响；基于ABAQUS建立26组不同钢纤维掺量钢管混凝土柱模型，根据现场试验结果验证模型的正确性，分析其中6组钢纤维掺量对其轴压性能的影响，并建立不同钢纤维掺量下钢管混凝土柱轴压承载力计算公式。结果表明，2 % 掺量钢纤维对自密实混凝土强度增长的贡献较为显著，并能提高约4 % 自密实钢管混凝土柱轴压承载力，为最适宜掺量。提出考虑钢纤维掺量对钢管混凝土强度提高的计算式，与试验结果吻合良好。

Abstract: In order to improve the axial compression bearing capacity of concrete filled steel tubular columns, steel fibers were added into self-compacting concrete.Through orthogonal test, the influence of 3 groups of steel fiber content on the strength of self-compacting concrete is studied, and the basis for the steel fiber content of concrete filled steel tube is provided.The axial compression tests of steel fiber reinforced concrete filled steel tubular columns and ordinary steel fiber reinforced concrete filled steel tubular columns were carried out to study the influence of steel fiber on the axial compression properties of self-compacting concrete filled steel tubular columns.Based on ABAQUS, 26 groups of concrete-filled steel tubular column models with different steel fiber content are established.After the correctness of the model is verified according to the field test results, the influence of six groups of steel fiber content on its axial compression performance is analyzed, and the calculation formula of the axial compression bearing capacity of concrete-filled steel tubular column with different steel fiber content is established.The results show that 2 % steel fiber has a significant contribution to the strength growth of self-compacting concrete, and can increase the axial compression bearing capacity of self-compacting concrete filled steel tubular columns by about 4 %.The calculation formula considering the increase of steel fiber content to the strength of concrete filled steel tube is proposed, which is in good agreement with the test results.
