Whole-Span and Whole Length Pre-Stress Loss Monitoring Technique Study in Bonded Pre-Stressed System

Abstract:

The load of pre-stress structure comes from stretching of steel strand, but the stress built on the steel strand would be lost. The lost causes many problems on the structure, such as pre-stress uneven and margin of safety reduced. Monitoring stress lever on the steel strand can provide information of the structure, and then expert can estimate the behavior under load of structure. It is hardly to monitor the whole-span and whole length of steel strand by traditional senses and method, because of measure range, protection and interference of electromagnetic environment. A novel method based on Optic Fiber Bragg Grating (OFBG), which mentioned in the article, provides a successful experience on the monitoring of pre-stress loss in whole-span and whole length.
