| Abstract: | The Fiber Bragg Grating(FBG) sensors in the center of die are pultruded with fiber strands in the production of Fiber Reinforced Polymer(FRP) bars,and the smart Fiber Bragg Grating-Fiber Reinforced Polymer(FBG-FRP) anchor tendons are produced.In this paper,the sensor mechanisms and characteristics of FBG-FRP anchor tendons are studied.The results show that the FBG-FRP anchor tendons have perfect properties of high tensile strength and low weight and excellent corrosion resistance and self-monitoring,which can be applied to many civil engineering such as mine,foundations,excavations,concrete dams,airports,aerodrome tunnels,ports,retaining wall,bridge abutments and so on.It is proved that it is feasible to use FBG-FRP technology monitoring anchor system safety and providing warning. |
