    This work shows how the experimental strain data obtained with an OBR (Optical Backscattered Reflectometer) measuring system can be used to locate cracking before being visually observable and also to estimate the crack ...
  • Cracking assessment in concrete structures by distributed optical fiber 

    Rodríguez, Gerardo; Casas Rius, Joan Ramon; Villalba Herrero, Sergi (2015-03)
    Article
    Open Access
    In this paper, a method to obtain crack initiation, location and width in concrete structures subjected to bending and instrumented with an optical backscattered reflectometer (OBR) system is proposed. Continuous strain ...
