Abstract:
1. A system for post-tensioned tendon monitoring comprising: at least one optical sensor, which comprises a sensor array, arranged in monitoring proximity to a post-tensioned tendon; wherein said sensor array comprises: a test instrument in communication with the at least one optical sensor; a processor capable of managing operation of: a database stored on the storage device, wherein the database is adapted to contain sensor baseline information and sensor measurement data; wherein the test instrument is capable of sending a first wavelength to the at least one optical sensor and receiving a second wavelength from the at least one optical sensor, wherein at least one of the instrument or the processor is configured to analyze the second wavelength and output sensor measurement data for storage in the database; and wherein the processor is adapted to access the database and configured to calculate an amount of tensile loading which exists in the post-tensioned tendon, based on the sensor measurement data and the sensor baseline data, and to provide an output to the display indicative of a feature of the tensile loading which exists in the post-tensioned tendon.
