Embedded fiber-optic sensors in reinforced concrete beams for post event structural assessment
Reinforced concrete structural components are subjected during their service life to different loading conditions that may affect their durability and efficiency. This can reduce the safety level of the structure over the time until it degrades completely up to its ultimate limit state. In particular, reinforced concrete elements can develop cracking due to seismic loading leading to the exposure of the reinforced concrete elements to the aggression of external agents. Therefore, their post-earthquake structural assessment can be a procedure of great interest to ensure the durability and efficiency of existing reinforced concrete structures, especially when important and strategic buildings and infrastructural systems are considered. Being able to monitor the development and evolution of cracking may be crucial and this research is aimed at this purpose. In particular, laboratory tests are described on reinforced concrete beams equipped with distributed fiber optics sensors to monitor the state of cracking and its thickness propagation. The main objectives of the research can be summarized as (i) deformation and temperature development from concrete casting, (ii) crack detection and localization with distributed FOS, (iii) comparing sensing cables design and digital image correlation procedures.
