Composite Bridge Girders Structure Health Monitoring Based on the Distributed Fiber Sensing Textile
نویسندگان
چکیده
Distributed structure health monitoring has been a hot research topic in recent years, and optic fiber sensors are largely developed for the advantages of high sensitivity, better spatial resolution, small sensor size. However, limitation fibers installation reliability become one major drawbacks this technology. This paper presents sensing textile new method inside bridge girders to address those shortcomings systems. The was utilized monitor strain distribution Grist Mill Bridge located Maine based on Brillouin Optical Time Domain Analysis (BOTDA). A modified slider increase efficiency confined girders. girder’s response successfully recorded by during loading tests that involved four trucks bridge. demonstrated capability differentiate separated locations. These results demonstrate way installing potential applications textiles structural monitoring.
