FRP加固木梁抗弯性能研究进展

RESEARCH PROGRESS ON FLEXURAL PROPERTIES OF FRP-REINFORCED WOODEN BEAMS

木梁是木结构中主要受力构件之一,进行木梁加固对于加强结构的整体稳定性尤为重要。目前FRP加固技术在木梁加固领域被广泛应用和研究,文中依据不同加固方法,分类总结已有的FRP加固木梁的研究成果,分析FRP布加固完好和损伤木梁的受弯性能以及FRP筋/片加固木梁的受弯性能,并进行了对比研究。最后提出了仍存在的不足并给出进一步研究的建议,以期为木结构的保护提供参考。

Wooden beams are one of the main load-bearing elements in wood structures,reinforcement of which is particularly important to enhance the overall stability of the structure.The FRP reinforcement technology is widely used and studied in the field of wood beam reinforcement.In this paper,the existing research results of FRP rein⁃forced wood beams are classified and summarized according to different reinforcement methods.The flexural perfor⁃mance of FRP cloth reinforced intact and damaged wood beams,and the flexural performance of FRP tendon/chip re⁃inforced wood beams are analyzed.Finally,the shortcomings still exist and suggestions for further research are given to provide the reference for the protection of wooden structures.
