| 摘 要： | FRP筋以其耐腐蚀、抗拉强度高、松弛小等特点,在暴露及恶劣条件下的预应力结构中有非常广阔的前景.目前国内外对预应力FRP筋混凝土结构的静力性能已有较多研究,而对于预应力FRP筋混凝土结构的疲劳性能研究,在国外刚刚起步,在国内则是空白.本文在系统地查阅国外最新研究资料的基础上,对FRP筋的疲劳性能、预应力FRP筋混凝土梁的疲劳性能进行了研究与总结,并对今后的发展趋势作了展望.

| Abstract: | The advantages of utilizing FRP in engineering are summarized into good resistance to corrosion,high strength and little relaxation,etc.So it is very promising for the prestressed concrete structures to be used in bad conditions.There have been plenty of studies on the static behavior of concrete beams prestressed with FRP rebars all over the world.However,for the fatigue behavior of this structure only a few institutions abroad are working on this subject,and it is still blank in China.In this paper,based on the summarization of foreign studies,the fatigue performance of FRP tendons and concrete beams prestressed with FRP rebars is studied.In the end the issue necessarily to be solved is presented. |
