| 摘 要： | 对5根采用玄武岩纤维布和碳纤维布加固的混凝土短柱和1根对比柱进行了低周反复荷载试验.试验表明,玄武岩纤维布环向包裹加固能显著改变混凝土短柱的破坏形态,提高混凝土短柱的抗剪承载力、延性和耗能能力.相同工况下,玄武岩纤维布加固短柱的抗震性能与碳纤维布加固的短柱相近.玄武岩纤维布因低廉的价格和较好的综合力学性能,在抗震加固领域将有较好的应用前景. |
| 关 键 词： | 混凝土 短柱 抗震性能 玄武岩纤维 碳纤维 |

| Abstract: | Low cyclic loading test is conducted on one comparative short column and five reinforced concrete(RC) short columns strengthened with basalt fiber reinforced plastic(BFRP) and carbon fiber reinforced plastic(CFRP). The tests show that failure modes, shear strength, ductility and energy dissipation are improved and increased for specimens strengthened with BFRP. On the same condition, various short columns strengthened with BFRP and CFRP give similar seismic performance. But BFRP has a good perspective for its low cost and good comprehensive mechanical properties in seismic strengthening field. |
| Keywords: | concrete short column seismic performance carbon fiber reinforced plastic(CFRP) basalt fiber reinforced plastic(BFRP) |
