Current study status of FRP reinforced concrete beams
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.
