To the issue of monitoring of metal-bearing bridges supporting fiber optic sensors
Keyword(s):
This article describes results of studies on the monitoring of deformations of load-bearing metal structures of a span structure of a bridge using fiber-optic sensors based on fiber Bragg gratings before and after reinforcement by polymer composite materials. It is received, that as a result of strengthening the deflection of the bridge has decreased in 2 times. The results of the experimental studies were compared with the computational justification carried out in PC LIRA 10.8. As a result of experimental and theoretical studies it was confirmed that the installed reinforcement system using composite spigots can be effectively used to restore the bearing capacity of artificial structures.
