摘　　要：传统的木梁加固方法有铁件加固、修整加固等,但因它存在自重大、耐腐蚀性差等缺点,使传统加固越来越少被用于实际应用中。与之相比,FRP加固技术具有轻质高强、耐久性好等优点,在未来的木结构加固中具有广泛的应用前景。文中详细叙述了国内外不同FRP材料加固残损木梁、完整木梁以及拼接木梁的研究成果和结论,并进行了对比研究。研究表明无论是经FRP布加固还是FRP板加固,完好木梁、损伤木梁以及拼接木梁的承载力和延性均有所提高,其加固效果主要与粘贴层数、粘贴方向以及是否施加预应力等因素有关。文中在最后提出仍存在的不足之处并给出建议,以期为木结构的保护提供依据。Traditional methods for reinforcing wooden beams,such as using iron fittings or reshaping techniques,are less commonly applied in practice due to drawbacks like heavy weight and poor corrosion resistance.In contrast,fiber reinforced polymer(FRP)reinforcement technology offers advantages such as light weight,high strength,and good durability,making it a promising solution for future wooden structure reinforcement applications.This paper provides a detailed review of domestic and international research on using various FRP materials to reinforce dam⁃aged,intact,and spliced wooden beams.The results indicate that both FRP fabric and FRP plate reinforcement sig⁃nificantly improve the load-bearing capacity and ductility of intact,damaged,and spliced wooden beams.The effec⁃tiveness of the reinforcement is primarily influenced by factors such as the number of FRP layers applied,the direc⁃tion of application,and whether prestressing is introduced.Finally,the paper highlights existing limitations and of⁃fers suggestions for future research,aiming to provide a foundation for the preservation of wooden structures.
