摘　　要：针对FRP筋具有高强、轻质、抗腐蚀、耐疲劳等优点,但其弹性模量低的现状,提出了采用对FRP筋施加预应力,以充分发挥其抗拉强度的技术,并针对国内预应力FRP筋混凝土梁的短期刚度进行了综述。Aimming at the actuality that FPR bar has some merits, such as high intensity, lightweight, anti-corrupting, fatigue-resistant and so on, but has low spring module, adopting the technique of inflicting prestressed to FRP bar is brought forward, in order to exert its anti-pulls intensity, adequately,and summarize the short-term sliffness of domestic prestressed FRP bar concrete beam,
