FRP加固钢筋混凝土梁疲劳性能的分析

Fatigue performance research of reinforced concrete beam strengthened with FRP

随着FRP材料越来越多的用于诸如公路、铁路桥等这类长期承受疲劳荷载作用的梁式钢筋混凝土结构的加固修复中,对使用FRP加固的钢筋混凝土结构疲劳性能研究,也越来越受到国内外相关学者和工程技术人员的关注。对加固后结构的疲劳性能的研究,也是对现有的FRP加固RC结构研究内容的有力补充,使现有FRP加固钢筋混凝土结构的研究内容更为完整。本文结合现有实验,从理论上较完整地分析了FRP加固钢筋混凝土梁的疲劳性能。

Following the increasingly use of the FRP materials in the repairing of this kind of steel reinforced concrete structures, especially the beam kind structures such as highway and railway bridges, which have long-term withstanding fatigue load. The research on the fatigue performance of this kind of FRP reinforced RC beam also receives more and more attentions by the domestic and foreign correlative scholars and the engineers and technicians universally. And the research on this durable question of fatigue performance is a powerful supplement to the existing research contents of FRP repaired RC structures, making it a complete theory system. This paper studies the fatigue performance of FRP reinforced RC beams in theory with specific experiments.
