The sensing principle was based on transmission modes theory. The natural frequency of an RC beam was theoretically analyzed. Experiments were carried out with sensors mounted on the surface or embedded in the RC beam. Vibration detection results agreed well with Kistler accelerometers. The experimental results found that both the accelerometer and TPFS detected the natural frequency function of a vibrated RC beam well. The mode shapes of the RC beam were also found by using the TPFSs. The proposed vibration detection method provides a cost-comparable solution for a structural health monitoring (SHM) system in civil engineering.<\/jats:p>","DOI":"10.3390\/s16122149","type":"journal-article","created":{"date-parts":[[2016,12,16]],"date-time":"2016-12-16T10:55:28Z","timestamp":1481885728000},"page":"2149","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Tapered Polymer Fiber Sensors for Reinforced Concrete Beam Vibration Detection"],"prefix":"10.3390","volume":"16","author":[{"given":"Dong","family":"Luo","sequence":"first","affiliation":[{"name":"School of Human Settlements and Civil Engineering, Xi\u2019an JiaoTong University, Xi\u2019an 710049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zainah","family":"Ibrahim","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Faculty of Engineering, University of Malaya, Kuala Lumpur 50603, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianxun","family":"Ma","sequence":"additional","affiliation":[{"name":"School of Human Settlements and Civil Engineering, Xi\u2019an JiaoTong University, Xi\u2019an 710049, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zubaidah","family":"Ismail","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, Faculty of Engineering, University of Malaya, Kuala Lumpur 50603, Malaysia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"David","family":"Iseley","sequence":"additional","affiliation":[{"name":"Director of Trenchless Technology Center (TTC), Louisiana Tech University, 599 Dan Reneau Dr., Engineering Annex, Ruston, LA 71272, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2016,12,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"483","DOI":"10.1111\/j.1467-8667.2011.00718.x","article-title":"A synchronized wireless sensor network for experimental modal analysis in structural health monitoring","volume":"26","author":"Bocca","year":"2011","journal-title":"Comput.-Aided Civ.
