预应力高强纤维布加固技术及其工程实践

Strengthening technology with prestressed FRP and practical application

探讨了FRP加固混凝土结构的缺陷,提出通过施加预应力和改变粘结层性能来克服FRP现有加固技术缺陷的方法,试验表明,这一技术能方便、可靠地将各类FRP张拉至理想的应力状态,结合实际工程提出了预应力FRP加固混凝土构件的施工工艺。

This paper discusses the defects of the concrete structure of the FRP reinforcement, and puts forward the method of applying prestressing and changing the coherence layer to conquer these defects FRP. The tests have shown that these equipments can tension all kinds of FRP fabrics to an ideal stressing condition. Meanwhile, the authors bring forth the construction technique of strengthening technology with prestressed FRP.
