摘　　要：FRP筋具有优异的耐腐蚀性能,同时具有抗拉强度高、疲劳性能优、徐变松弛性能好等优良力学性能,适用于替代普通钢筋和预应力钢筋用于腐蚀环境和特殊工程。介绍了FRP筋的力学性能及其与混凝土、纤维混凝土的粘结性能,并对FRP筋梁、FRP筋与钢筋混合配筋梁、FRP金属复合筋梁、ECC-FRP筋混凝土复合梁的国内外研究现状进行了总结。FRP bars have excellent behaviors,such as corrosion resistance,high tensile strength,excellent fatigue properties, good creep relaxation properties and many other excellent mechanical properties. So,it is an alternative to normal steel bars and prestressed steel bars in corrosive environments and other special projects. The mechanical behaviors of FRP bars and its bond behavior with concrete and fiber reinforced concrete were introduced, current research status of concrete beams reinforced with FRP bars,concrete beams hybrid reinforced with FRP bars and steel bars,concrete beams reinforced with FRP-steel composite bars and ECC-RC composite beams reinforced with FRP bars were introduced in his paper.
