Paper Abstract

The design operation and testing of a simple Class II laser optical fiber structural monitoring system and associated instrumentation is discussed. The response of this monitoring system was observed for optical fibers embedded in the tensile and compressive sides of a 100mm X 1500mm reinforced concrete beam during curing and laser under test load conditions. The internal temperature of the specimen was monitored throughout the curing process using thermocouples and this data correlated with the transmission intensity data obtained from the fibers. For he load tests, conventional electronic strain gauges were placed near the optical fibers; the fiber sensor system displayed a negative linear response. Thus, simple optical fiber sensor systems may be considered as possible alternatives to existing methods for monitoring the structural integrity of concrete infrastructures. The use of optical fibers have several inherent advantages in their own right including immunity form electromagnetic interference and ensuring the integrity of readings form around power cables and transformers. Also, the potential for long distributed sensor in environments such as tunnels is well suited to the deployment of optical fiber sensor technology.
