FRP筋混凝土结构抗震性能的研究现状综述

Review of research on seismic behavior of concrete structures reinforced with FRP bars

随着对FRP筋材料受力性能研究的深入,采用FRP筋替代钢筋和预应力筋运用于混凝土结构中,用来提高钢筋混凝土结构受力性能有着广泛的应用前景。但是FRP筋具有弹性模量低和破坏时脆性大等特点,限制了其在震区结构工程中的应用。文章主要介绍了FRP筋混凝土结构的粘结性能,并总结了国内外关于FRP筋混凝土柱、剪力墙和框架混凝土结构抗震性能的研究成果,并提出了今后研究的方向。

With the development of the research on the mechanical properties of FRP bars,the mechanicalproperties of reinforced concrete structures by are improved by using FRP bars instead of steel bars andprestressed tendons. They have a wide application prospect. However, FRP bars have the characteristics of lowelastic modulus and high brittleness, which limits their application in structural engineerings. This paper mainlyintroduces the bond performance of FRP reinforced concretethe seismic performance of FRP reinforced concrete columns,and abroad, and the direction for future research is presented.structure, and summarizes the research results onshear wails and frame concrete structures at homeand abroad, and the direction for future research is presented.
