摘要/Abstract

摘要： 与传统加固方法相比,FRP加固技术具有轻质高强、操作简便、耐久性好等特点,在木结构加固中具有重要的应用前景。详细叙述了国内外FRP加固木结构受压、受弯和受剪性能的研究方法和得到的结论,介绍了FRP加固木结构技术在建筑和桥梁中的应用概况。在总结已有研究中缺乏FRP对木柱约束效应、考虑木结构实际应力应变模型的加固木梁受弯性能及FRP加固木梁受剪性能三个方面研究的基础上,提出针对这三个方面进一步研究不同加固方式和加固参数对FRP加固木结构受力性能影响的建议,为制定FRP加固木结构标准奠定基础。

Abstract: Using FRP (Fiber Reinforced Polymer) to reinforce wood structures has the properties of light weight, high strength, easy manipulation and high durability, comparing with the traditional methods. Therefore, the study on FRP reinforcing wood structures has the practical significance. The research methods and conclusion about compression, flection and shear behavior of wood structures reinforced with FRP are described in detailed. Application of technology of FRP reinforcing wood structures in architecture and bridge is introduced. The lack of research is bound effect of FRP on the wood column, the flection property of reinforced wood beam on the basis of the actual stress-strain model and the shear property of the wood beam reinforced with FRP. The further research about the influence of the methods and design parameters on the behavior of strengthened wood members is proposed to formulate standard of FRP reinforcing wood structures.

Key words: FRP, wood structure, arrangement way, mechanical performance
