Field static and dynamic load tests were conducted on a bridge consisting of a span with newly replaced PCI girders and numerous spans with old PCI girders. Both the static and dynamic test results showed that the flexural rigidity of the old PCI girders decreased significantly due to deterioration. To improve the efficiency of on-site monitoring data transmission and data analysis, this study developed a smart dynamic strain gauge node with the function of edge computing. Continuous data with a sampling frequency of 100 Hz were computed at the sensor node. Among the computed results, only the maximum dynamic strain data caused by the passage of the heaviest vehicle within 1 min were transmitted. The on-site monitoring results indicated that under routine traffic conditions, the dynamic strain response of the new PCI girder was smaller than that of the deteriorated PCI girder. When the monitored dynamic strain response has a tendency to magnify, attention should be paid to the potential prestress loss or other deterioration behaviors of the bridge.<\/jats:p>","DOI":"10.3390\/s22228711","type":"journal-article","created":{"date-parts":[[2022,11,14]],"date-time":"2022-11-14T04:30:52Z","timestamp":1668400252000},"page":"8711","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Application of Edge Computing in Structural Health Monitoring of Simply Supported PCI Girder Bridges"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5533-4249","authenticated-orcid":false,"given":"Yi-Ching","family":"Lin","sequence":"first","affiliation":[{"name":"Department of Civil Engineering, National Chung Hsing University, 145 Xingda Rd., South Dist., Taichung 402, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chin-Yu","family":"Hsiao","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, National Chung Hsing University, 145 Xingda Rd., South Dist., Taichung 402, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian-Hua","family":"Tong","sequence":"additional","affiliation":[{"name":"Department of Computer Science and Information Engineering, Hungkuang University, No. 1018, Sec. 6, Taiwan Boulevard, Shalu District, Taichung 433, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chih-Pin","family":"Liao","sequence":"additional","affiliation":[{"name":"The Second Maintenance Office, Directorate General of Highways, No. 127, Daquan St., West Dist., Taichung 403, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shin-Tai","family":"Song","sequence":"additional","affiliation":[{"name":"Department of Civil Engineering, National Chung Hsing University, 145 Xingda Rd., South Dist., Taichung 402, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hsin-Chu","family":"Tsai","sequence":"additional","affiliation":[{"name":"China Engineering Consultants, Inc., Floor 28, No. 185, Section 2, Sinhai Road Da-an Dist., Taipei City 106, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jui-Lin","family":"Wang","sequence":"additional","affiliation":[{"name":"China Engineering Consultants, Inc., Floor 28, No. 185, Section 2, Sinhai Road Da-an Dist., Taipei City 106, Taiwan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,11,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"257","DOI":"10.1177\/1475921703036169","article-title":"Review Paper: Health Monitoring of Civil Infrastructure","volume":"2","author":"Chang","year":"2003","journal-title":"Struct.
