Abstract
Fiber Bragg grating and resistance strain gauge have been used to test the stress change in key parts of structure of 61t-55m quayside container crane under the same testing conditions. The testing data and stress-time history diagrams obtained by the resistance strain gauge and fiber Bragg grating have been analyzed. The results verify good real-time property and high reliability of the structural health monitoring system based on fiber Bragg grating system.
