Two sensor installation methods are compared: (1) attaching the sensor along the bar and (2) winding the sensor on the bar. For the second method, optical fibers were winded spirally on steel bars with different spacings: 0 mm, 2 mm, 5 mm, and 10 mm. Steel bar pull-out testing was conducted to evaluate the effect of presence of distributed sensor on the bond strength of steel\u2013concrete interface. Electrochemical testing was carried out to assess the influence of the installation methods on the corrosion resistance of the reinforced concrete. Winding the optical fiber on steel bars with a 10-mm spacing does not affect the bond strength and corrosion resistance and allows real-time corrosion monitoring. The distributed sensor data can be used to estimate the corrosion induced steel loss and predict concrete cracking.<\/jats:p>","DOI":"10.3390\/s18113722","type":"journal-article","created":{"date-parts":[[2018,11,1]],"date-time":"2018-11-01T11:31:47Z","timestamp":1541071907000},"page":"3722","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":37,"title":["Feasibility of Distributed Fiber Optic Sensor for Corrosion Monitoring of Steel Bars in Reinforced Concrete"],"prefix":"10.3390","volume":"18","author":[{"given":"Liang","family":"Fan","sequence":"first","affiliation":[{"name":"Department of Civil, Architectural and Environmental Engineering, Missouri University of Science and Technology, Rolla, MO 65401, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yi","family":"Bao","sequence":"additional","affiliation":[{"name":"Department of Civil, Environmental and Ocean Engineering, Stevens Institute of Technology, Hoboken, NJ 07030, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Genda","family":"Chen","sequence":"additional","affiliation":[{"name":"Department of Civil, Architectural and Environmental Engineering, Missouri University of Science and Technology, Rolla, MO 65401, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2018,11,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1507","DOI":"10.1016\/j.cemconres.2010.06.004","article-title":"Laboratory investigation of reinforcement corrosion initiation and chloride threshold content for self-compacting concrete","volume":"40","author":"Yu","year":"2010","journal-title":"Cem.
