The use for terrestrial laser scanning data for deformation monitoring has earlier been tested although conventional surveying technologies are still more preferred. Since terrestrial laser scanners are capable of acquiring a large amount of highly detailed geometrical data from a surface it is of interest to study the metrological advantages of the terrestrial laser scanning technology for deformation monitoring of structures. The main intention of this study is to test the applicability of terrestrial laser scanning technology for determining range and spatial distribution of deformations during bridge load tests. The study presents results of deformation monitoring proceeded during a unique bridge load test. A special monitoring methodology was developed and applied at a static load test of a reinforced concrete cantilever bridge built in 1953. Static loads with the max force of up to 1961 kN (200 t) were applied onto an area of 12 m\u00b2 in the central part of one of the main beams; the collapse of the bridge was expected due to such an extreme load. Although the study identified occurrence of many cracks in the main beams and significant vertical deformations, both deflection (\u20134.2 cm) and rising (+2.5 cm), the bridge did not collapse. The terrestrial laser scanning monitoring results were verified by high-precision levelling. The study results confirmed that the TLS accuracy can reach \u00b12.8 mm at 95% confidence level.<\/jats:p>","DOI":"10.3846\/bjrbe.2015.03","type":"journal-article","created":{"date-parts":[[2015,4,12]],"date-time":"2015-04-12T16:25:47Z","timestamp":1428855947000},"page":"17-27","source":"Crossref","is-referenced-by-count":28,"title":["Geodetic monitoring of bridge deformations occurring during static load testing"],"prefix":"10.7250","volume":"10","author":[{"given":"Tarvo","family":"Mill","sequence":"first","affiliation":[{"name":"Tallinn University of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Artu","family":"Ellmann","sequence":"first","affiliation":[{"name":"Tallinn University of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Martti","family":"Kiisa","sequence":"first","affiliation":[{"name":"Tallinn University of Applied Sciences"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juhan","family":"Idnurm","sequence":"first","affiliation":[{"name":"Tallinn University of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Siim","family":"Idnurm","sequence":"first","affiliation":[{"name":"Tallinn University of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Milan","family":"Horemuz","sequence":"first","affiliation":[{"name":"Royal Institute of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrus","family":"Aavik","sequence":"first","affiliation":[{"name":"Tallinn University of Technology"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"4297","reference":[{"key":"key-10.3846\/bjrbe.2015.03.-1","doi-asserted-by":"publisher","DOI":"10.1109\/BEIAC.2013.6560128"},{"key":"key-10.3846\/bjrbe.2015.03.-2","article-title":"Comparison of Techniques for Terrestrial Laser Scanner Data Georeferencing Applied to 3-D Modeling of Cultural Heritage","volume-title":"Proc. of the 3D-ARCH 2007 \u201cVirtual Reconstruction and Visualization of Complex Architectures\u201d","author":"Alba, M.","year":"2007"},{"key":"key-10.3846\/bjrbe.2015.03.-3","doi-asserted-by":"publisher","DOI":"10.3846\/20296991.2013.840356"},{"key":"key-10.3846\/bjrbe.2015.03.-4","doi-asserted-by":"publisher","DOI":"10.1016\/j.autcon.2010.12.008"},{"key":"key-10.3846\/bjrbe.2015.03.-5","volume-title":"Testing of Concrete in Structures","author":"Bungey, J.
