预应力CFRP加固钢梁抗弯性能的研究进展

Research Progress on Flexural Behavior of Steel Beams Strengthened with Prestressed CFRP

钢结构作为一种具有众多优势的建筑材料,被广泛应用于工程建设中,在使用过程中不可避免地需要进行加固。现阶段,对钢结构加固的方式有很多,各自有着不同的优缺点,但主要还是用于提高钢结构在使用过程中的抗弯性能。同时,在传统加固方式的基础上,发展出了预应力CFRP板加固钢结构的方式,通过比较不同预应力CFRP板加固方式,总结发现,预应力CFRP板在提高钢梁抗弯性能方面有着显著优势。

As a kind of building material with many advantages,steel structure is widely used in engineering construction,and reinforcement is inevitable in the use process.At present,there are many ways to strengthen the steel structure,each has different advantages and disadvantages,but mainly used to improve the bending performance of steel structure in the use process.At the same time,on the basis of the traditional strengthening methods,the prestressed CFRP plate is developed to strengthen the steel structure.By comparing different strengthening methods of prestressed CFRP plates,it is concluded that prestressed CFRP plates have significant advantages in improving the flexural performance of steel beams.
