This article quantitatively evaluates the safety state of a fabricated small box girder bridge in Wuhan City based on Fuzzy Analytic Hierarchy Process (FAHP) and structural health monitoring (SHM) data. Firstly, the FAHP model is established, and stress, deformation, and temperature are selected as evaluation factors. The safety thresholds of stress and deformation are determined by combining the industry specifications and the historical statistical patterns of the massive SHM data. The temperature field of the bridge is simulated and analyzed by combining ANSYS, HYPERMESH, and TAITHREM, and the most unfavorable temperature gradient is determined as a threshold for the safety evaluation. Finally, the scores of indexes of the bridge are determined based on the measured SHM data, which in turn provides a quantitative description of the safety state. The results show that the thresholds determined by the joint industry specifications and the massive SHM data are reasonable; the temperature field simulation model established in this article is consistent with the measured results, and can accurately determine the temperature gradient of the bridge. The safety evaluation result from the FAHP model is the same as the field test results, which verifies the effectiveness and applicability of the proposed method to actual bridge projects.<\/jats:p>","DOI":"10.3390\/s24144592","type":"journal-article","created":{"date-parts":[[2024,7,15]],"date-time":"2024-07-15T22:17:32Z","timestamp":1721081852000},"page":"4592","source":"Crossref","is-referenced-by-count":0,"title":["Safety Evaluation for Fabricated Small Box Girder Bridges Based on Fuzzy Analytic Hierarchy Process and Monitoring Data"],"prefix":"10.3390","volume":"24","author":[{"ORCID":"http:\/\/orcid.org\/0000-0002-7078-7705","authenticated-orcid":false,"given":"Hongyin","family":"Yang","sequence":"first","affiliation":[{"name":"School of Civil Engineering and Architecture, Wuhan Institute of Technology, Wuhan 430073, China"},{"name":"Hubei Provincial Engineering Research Center for Green Civil Engineering Materials and Structures, Wuhan 430073, China"}]},{"ORCID":"http:\/\/orcid.org\/0009-0003-8853-6095","authenticated-orcid":false,"given":"Liangwei","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Civil Engineering and Architecture, Wuhan Institute of Technology, Wuhan 430073, China"}]},{"given":"Feng","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Civil Engineering and Architecture, Wuhan Institute of Technology, Wuhan 430073, China"}]},{"ORCID":"http:\/\/orcid.org\/0000-0001-5449-4921","authenticated-orcid":false,"given":"Jianfeng","family":"Gu","sequence":"additional","affiliation":[{"name":"School of Civil Engineering and Architecture, Wuhan Institute of Technology, Wuhan 430073, China"}]},{"given":"Zhongtao","family":"Ye","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Bridge Intelligent and Green Construction, Wuhan 430034, China"}]},{"given":"Ya","family":"Peng","sequence":"additional","affiliation":[{"name":"School of Civil Engineering and Architecture, Wuhan Institute of Technology, Wuhan 430073, China"}]},{"given":"Zhangjun","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Civil Engineering and Architecture, Wuhan Institute of Technology, Wuhan 430073, China"}]},{"given":"Renhui","family":"Cheng","sequence":"additional","affiliation":[{"name":"School of Civil Engineering and Architecture, Wuhan Institute of Technology, Wuhan 430073, China"}]}],"member":"1968","published-online":{"date-parts":[[2024,7,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Gautam, B.G., Xiang, Y., Liao, X., Qiu, Z., and Guo, S.
