Abstract

It is especially important to monitor the health of steel strand wires, which are the main load-bearing component of engineering structures. The emergence of groove embedding packaging technique for fiber grating sensors (FBGs) has achieved the integration of stress and monitoring of steel strands. To investigate the effect of groove embedding packaging technique on the relaxation performance of steel strands and steel wires, this paper conducted isothermal relaxation tests on round steel strands, epoxy steel strands, and galvanized steel wires. The results indicate that engraving grooves cannot significantly improve the relaxation rate of steel strands, while the process of untwisting, heavy twisting, and repeated tensioning has a significant influence on the relaxation rate of steel strands.
