摘要
通过对5根玄武岩纤维钢管C70混凝土短柱和1根普通钢管C70混凝土短柱进行轴心受压试验,研究了玄武岩纤维掺量和长径比对玄武岩纤维钢管C70混凝土短柱力学性能的影响。结果表明:掺入玄武岩纤维后,钢管C70混凝土短柱极限承载力有一定程度的提高,延性有所增大;但掺入玄武岩纤维对钢管C70混凝土短柱破坏模式的影响不明显。
The tests of five basalt fiber（ BF） reinforced C70 concrete filled steel tubular short columns and one C70concrete filled steel tubular short column under axial compression load were carried out. The influence of different dosages and length-diameter ratio of BF on the mechanical property of the basalt fiber reinforced C70 concrete filled steel tubular short columns were discussed. The results indicated that the ultimate load-bearing capacity and the ductility of short columns are improved by BF in concrete,but the failure mode of short columns is not affected obviously by BF in concrete.
