摘要: 为分析玄武岩纤维布加固混凝土短柱的抗剪承载力和破坏形态,对1 根对比短柱和2根采用玄武岩纤维布加固的无损混凝土短柱进行了低周反复荷载试验。试验表明,玄武岩纤维布加固能显著改变短柱的破坏形态,提高短柱的抗剪承载力。基于现有试验数据和计算公式,提出了玄武岩纤维布加固混凝土短柱抗剪承载力的简化计算公式。

Abstract: To analyze shear bearing capacity and failure modes of RC short columns strengthened with BFRP. Low cyclic loading tests were conducted on one comparative short column and two no-destructive RC short columns strengthened with BFRP. The tests show that failure mode, shear strength, ductility are improved and increased for specimens strengthened with BFRP. Shear capacity calculation formula of RC short column strengthened with BFRP has proposed based on test results and current formulae.

Key words: BFRP, concrete, short column, failure mode, shear capacity
