When the span of a cross-line continuous bridge with a double-box girder was hit by an overly high vehicle, the concrete floor of one girder was severely damaged, and part of the prestressed strands and reinforcements in the girder were broken. After the double-box girder was removed and separated into two single box girders, the ultimate flexural capacity of both box girders was studied by destructive tests, and a comparison was made between the damaged and undamaged girders. Moreover, finite element analysis was conducted to simulate the failure process. The results show that the flexural bearing capacity of the damaged box girder decreased by 33%, but it was still 1.07 times greater than the design bearing capacity, which basically meets the design requirements. Also, the damaged box girder showed a desirable serviceable limit state for three-axle vehicles and five-axle vehicles, but showed an undesirable serviceable limit state for six-axle vehicles. This study shows that repairing or strengthening the damaged span may be better than demolishing and rebuilding the whole superstructure bridge.<\/jats:p>","DOI":"10.3390\/ma15113949","type":"journal-article","created":{"date-parts":[[2022,6,1]],"date-time":"2022-06-01T12:48:31Z","timestamp":1654087711000},"page":"3949","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Experimental-Numerical Study on the Flexural Ultimate Capacity of Prestressed Concrete Box Girders Subjected to Collision"],"prefix":"10.3390","volume":"15","author":[{"given":"Yong","family":"Li","sequence":"first","affiliation":[{"name":"Laboratory of Roads and Railway Engineering Safety Control, Shijiazhuang Tiedao University, Shijiazhuang 050043, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zijie","family":"Yu","sequence":"additional","affiliation":[{"name":"Laboratory of Roads and Railway Engineering Safety Control, Shijiazhuang Tiedao University, Shijiazhuang 050043, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qifan","family":"Wu","sequence":"additional","affiliation":[{"name":"Laboratory of Roads and Railway Engineering Safety Control, Shijiazhuang Tiedao University, Shijiazhuang 050043, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yongqian","family":"Liu","sequence":"additional","affiliation":[{"name":"Laboratory of Roads and Railway Engineering Safety Control, Shijiazhuang Tiedao University, Shijiazhuang 050043, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shang","family":"Wang","sequence":"additional","affiliation":[{"name":"Laboratory of Roads and Railway Engineering Safety Control, Shijiazhuang Tiedao University, Shijiazhuang 050043, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,1]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"103","DOI":"10.3141\/1696-50","article-title":"Diagnostic load tests of a prestressed concrete bridge damaged by overheight vehicle impact","volume":"1696","author":"Russo","year":"2000","journal-title":"Transp.
