摘要
试验研究了碳/玻璃纤维混杂布加固混凝土梁的抗弯性能,并与单一碳纤维布和玻璃纤维布加固梁进行了比较.结果表明,分别与单一碳纤维布和玻璃纤维布加固梁相比,碳/玻璃纤维混杂布加固梁的能量延性系数分别提高了24.0%和25.5%,表明混杂纤维布加固混凝土梁的延性显著优于单一纤维布加固混凝土梁.
The flexural performance of RC beam strengthened with carbon/glass fiber hybrid sheets is researched experimentally in this paper, and compared with that of RC beams strengthened with single carbon fiber sheet and single glass fiber sheet. The results show that compared with the RC beams strengthened with single carbon fiber sheet and single glass fiber sheet, the energy ductile index of RC beam strengthened with carbon/glass fiber hybrid sheets is respectively increased by 24.0 % and 25.5 % ,which indicate that the ductile of RC beam strengthened with hybrid fiber sheets is well significantly than that of RC beam strengthened with single fiber sheet.
