Distributed fiber-optic strain measurement - Application in reinforced concrete members

Distributed fiber-optic strain measurement – application in reinforced concrete members. Distributed fiber optic measurement based on Rayleigh scattering is a technique with new possibilities in the field of analysis and interpretation of experiments. However, the application is challenging and requires a lot of experience and practice. The measurement technique will be briefly described and subsequently the authors will show and explain the potential as well as challenges and limits of application based on two small experiments.
