摘要
为了研究用良好延性的混杂纤维增强聚合物(HFRP)加固腐蚀结构的可行性.研究了碳(CFRP)/芳纶(AFRP)/玻璃纤维(GFRP)层间混杂纤维布加固腐蚀梁的抗弯性能,结果表明:CFRP/AFRP/GFRP层间混杂纤维布加固腐蚀梁的开裂、屈服、峰值、极限荷载比未加固腐蚀梁分别提高了14%、35%、102%和109%,而位移延性系数降低了11%.在试验研究的基础上,给出了HFRP布加固腐蚀梁的承载力计算方法,理论计算值与试验值吻合良好.
In order to research the practicability of strengthening the corroded structure with good ductile hybrid fiber reinforced polymer(HFRP),the flexural performance of RC corroded beams strengthened with CFRP/AFRP/GFRP laminated hybrid fiber sheets is researched experimentally in this paper.The results show that compared with the RC corroded beam,the cracking load,yield load,maximum load and ultimate load of RC corroded beam strengthened with CFRP/AFRP/GFRP laminated hybrid fiber sheets respectively increased b...
