摘要
以高强玻璃纤维 (SGF)布与碳纤维 (CF)布混杂加固混凝土梁 ,进行对比试验研究 ,结果表明 ,与单一CF布加固相比 ,SGF/CF布混杂加固不仅使梁的延性显著提高 ,加固成本大幅降低 ,而且承载力也略有提高 ,仅刚度略为降低。
Test of comparison between the single carbon fibre strengthening concrete and strengthening reinforced concrete(RC) beams with hybrid carbon fibre(CF)and high strength glass fibre(SGF)and CF sheets strengthening concrete was carried out.It was shown from results that,the hybrid fiber reinforced polymer (HFRP) strengthening concrete beams obtained not only a significant increase of ductility but also a remarkable decrease of strengthening cost with a slight increase of load carrying capacity and a little decrease of stiffness compared with the CF sheet strengthened beams.The durability was briefly discussed as well.
