Therefore, the ageing of infrastructure demands the development of robust condition assessment methodologies based on affordable technology such as vehicle-induced vibration tests (VITs) in contrast with more expensive existing technologies such as tests using hammers or shakers. Ambient vibration tests (AVTs) have been widely used worldwide, taking advantage of freely available ambient excitation sources. However, the literature has commonly reported insufficient input energy to excite the structure to obtain satisfactory modal identification results, especially in long-span concrete bridges. On the other hand, the use of forced vibration tests (FVTs) requires more economic resources. This paper presents the results of field measurements at optimally selected locations in VITs consisting of a 32-ton truck and a springboard with a height of 50 mm. AVTs using optimal sensor placement (OSP) provide similar results to VITs without considering OSP locations. Additionally, the VIT\/AVT cost ratio is reduced to 2 since a shorter data collection time is achieved within a one-day (8 h) test framework, which minimizes temperature effects, thus leading to improvements in AVT identification results, especially in vertical modes.<\/jats:p>","DOI":"10.3390\/s22031219","type":"journal-article","created":{"date-parts":[[2022,2,6]],"date-time":"2022-02-06T20:40:18Z","timestamp":1644180018000},"page":"1219","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Vehicle Bump Testing Parameters Influencing Modal Identification of Long-Span Segmental Prestressed Concrete Bridges"],"prefix":"10.3390","volume":"22","author":[{"given":"Wilson","family":"Hernandez","sequence":"first","affiliation":[{"name":"School of Civil Engineering, Industrial University of Santander, Carrera 27 Calle 9, Bucaramanga 680002, Colombia"}]},{"given":"Alvaro","family":"Viviescas","sequence":"additional","affiliation":[{"name":"School of Civil Engineering, Industrial University of Santander, Carrera 27 Calle 9, Bucaramanga 680002, Colombia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7128-4165","authenticated-orcid":false,"given":"Carlos Alberto","family":"Riveros-Jerez","sequence":"additional","affiliation":[{"name":"Faculty of Engineering, University of Antioquia, Calle 67 No. 53-108, Medell\u00edn 050010, Colombia"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Ye, X., Chen, X., Lei, Y., Fan, J., and Mei, L.
