Abstract

Abstract

Traditional reinforcement maintenance methods are difficult to obtain the full-life cycle monitoring status of the bridge during the reinforcement process as well as the reinforcement effect. Therefore, a method for coupling a CFRP board with a pre-compressed long-range fiber bragg grating (FBG) sensor to make a self-sensing CFRP board was proposed. In order to test the stress and strain measurement accuracy of the fiber grating self-sensing CFRP board, based on the relevant calculation principle of national standard static performance index, the calibration and tension test of light grating sensing performance index in self-sensing CFRP plate were carried out, and the error of sensing characteristic theory and test strain sensitivity were analyzed. The test results showed that the fiber grating in self-sensing CFRP had good sensing performance, its strain reached more than 1.2×10^-2, the test strain sensitivity was not less than 1.18 pm/10^-6, the hysteresis was not more than 1.52%, the linearity was not more than 3.35%, and the repeatability was not more than 2.29%. The total accuracy was not more than 3.92%, which could meet the actual engineering requirements.
