摘要
芳纶纤维布由于良好的抗疲劳、抗弯折性和相对较低的价格使其在土木工程加固应用中有广阔的前景。本文采用OpenSees软件对芳纶纤维加固钢筋混凝土柱子进行低周反复加载模拟分析,并通过与未加固试件之间的比较分析了不同加固层数对试件的抗震性能的影响。研究结果表明:芳纶纤维加固墩柱能明显提高墩柱的抗震性能,但是抗震性能的提高程度与加固层数并不总是成正比关系。
Aramid fiber sheet is promising in the field of reinforcement engineering because of its excellent performance of fatigue resistance,bending resistance and relatively low price.OpenSees was introduced in this paper to analyze the seismic performances of AFRP retrofitted columns by applying low cycle repeated loading simulation.Moreover,the impact of reinforcement amount on seismic performance of RC columns was investigated with a comparison of unreinforced specimens.The results demonstrate that AFRP fibers can greatly promote the seismic performance of reinforced piers,however,the increase of the seismic performance is not always proportional to the reinforcement amount.
