摘要
普通纤维加固木结构不能充分利用纤维材料的高强性能,对于构件的变形也不能起到很好的降低作用,而对纤维材料施加一定的预应力将很好解决这些问题.本文对预应力纤维材料加固木梁进行了理论分析,给出在预应力条件下粘结应力的解析解,并提出简单实用的预应力施加方法——预弯法,为工程应用打下基础.
<Abstrcat> Fiber reinforced polymer (FRP) without prestress applied in the reinforcement of timber structures can't make full use of high strength of material, and reduce deformation of the structures obviously. However, prestressed FRP can overcome these disadvantages. In this paper, research of prestressed FRP in the reinforcement of timber structures is introduced, The analytic solutions of shear and normal stresses along the adhesive line are formulated and a useful introducing prestress method called pre-flex method is also proposed.
