“…Współcześnie można zaobserwować powrót do idei pomiaru przez przewodność. Rozwijane są równoległe dwie konkurencyjne koncepcje -pomiaru przez zmianę przewodności światła [2,4] i zmianę przewodnictwa elektrycznego [1].…”

“…The TCM has been verified extensively (Kenel, 2002;Kenel & Marti, 2002;Kenel et al, 2005) using optical fi bre Bragg Grating sensors at close spacing for the measurement of steel strains in reinforced concrete tension chords. As the optical fi bre was placed in a small slot milled along the rib-free side of the deformed bars, the bond between the bar and the surrounding concrete was largely unaffected.…”

“…measured the local strain of reinforcing steel bars by installing multiplexed FBGs along a 1 mm deep × 1 mm wide groove running through the side of a 10‐mm diameter bar. Their results measured the strain of the steel bars well into the plastic region and demonstrated that bond properties are much less affected when FBGs were used instead of traditional strain gauges due to the compactness of fiber optic lines . Continuous, distributed fiber optic sensors have also been recently investigated for use in monitoring RC and PC structures .…”
