摘要
介绍了国内外学者对FRP加固T梁和矩形截面梁(板)疲劳性能进行的试验研究,矩形梁包括锈蚀梁和未锈蚀梁,介绍了预应力FRP加固梁的疲劳性能。通过分析发现性价比更高的预应力混杂纤维加固材料使用较少,且未考虑腐蚀与疲劳的耦合作用以及试件的尺寸效应,这些都需要在今后进行进一步的试验研究。
This paper introduces experimental study of FRP-Reinforced T beam and rectangle beam （ including corrosion and no corrosion beam） or plate＇ s fatigue performance at home and abroad, and also introduces fatigue performance of beam reinforced by prestressed FRP. Through analysis, it is found that the reinforcement material of prestressed hybrid fiber has higher cost performance is used less, and found that coupling effect of corrosion and fatigue as well as dimensional effect of specimens is not be considered, so these things need farther experimental research in the future.
