Structural Integrity Monitoring of Concrete Structures via Optical Fiber Sensors: Sensor Protection Systems

Abstract

This paper reports on the design requirements and a range of specific concepts for optical fiber-based sensor protection systems that can be used in concrete structures. The designs range from sensor protection systems that are manufactured involving stainless steel, fiber reinforced composites and concrete. The feasibility of manufacturing the sensor protection systems using these materials is also demonstrated. A detailed finite element analysis was carried out to optimise the stainless steel-based sensor protection system for concrete. Experimental results involving the sensor protection system will be presented in Part 2 of this series of papers.
