Paper Abstract

Signal optical fiber is embedded in reinforced concrete structure to measure internal strain and vibration of structure using Mach-Zehnder interferometer. Calibration test is designed to identify material parameter of optical fiber, so internal strain of concrete structure is measured. In vibration test, amplitude and period of structure are measured, and vibration response property of structure is obtained. The experiment is verified using typical specimen. The research has important application prospect for the measurement of internal strain, vibration monitoring and damage assessment of structure.
