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．
