Abstract: The application of fiber Bragg grating(FBG)used in strain monitoring of reinforced concrete structure is studied.Strain coefficient and temperature coefficient were obtained.Static test of reinforced concrete beam equiped with FBG was done in order to study whose distinct sensing ability and monitor strains of the beam.A kind of steel tube packaged FBG was made to monitor the temperature only in order to study simultaneous measurement of strain and temperature.
