摘要

摘要: 采用正交试验设计方法,对9根钢管玄武岩纤维混凝土短柱进行轴心受压试验,研究玄武岩纤维掺量、含钢率和混凝土强度三个因素对短柱轴压性能的影响。试验结果表明:试件含钢率对其承载力影响显著,纤维掺量次之,混凝土强度影响不明显;混凝土强度等级为C60、纤维掺量为0.1%和钢管壁厚为6 mm时的承载力均比同因素下其他水平对应的值高;适当掺入玄武岩纤维可提高短柱承载力;随着含钢率的增加,短柱承载力与延性均有增大。

Abstract: The orthogonal tests of 9 basalt fiber ( BF) reinforced concrete filled steel tubular ( BFRCFST) short columns were carried out under axial compression load to investigate the influence of dosages of BF，steel ratio and concrete strength on behavior of BFRCFST short columns． The results indicated that the steel ratio had the most significant effect on bearing capacity of BFRCFST short columns，then dosage of BF，while concrete strength played a comparatively less important part; the bearing capacity of concrete strength C60，dosages of 0. 1% and steel tubular wall thickness 6 mm was higher than that of other level of the same factor． The proper dosages of BF were of advantage to improve the bearing capacity of BFRCFST short columns． BFRCFST short columns showed an increasing trend of the load bearing capacity and ductility with the steel ratio increasing．
