Monitoring of a concrete roof using terrestrial laser scanning
Keywords:deformation monitoring, terrestrial laser scanning, reinforced-concrete construction, singular value decomposition
AbstractThe paper deals with the geodetic monitoring of a parabolic shaped reinforced con-crete roof structure in the chemical company Duslo, Ltd. in Šaľa (Slovak Republic).The monitored structure is a part of the roof of a warehouse used for the storage offertilizer. The atmospheric conditions and the operation load caused deformationof the construction. For measurement was used the technology of terrestrial laserscanning. The displacements of the observed parts of the construction were cal-culated using planar surfaces by the procedure of Singular Value Decomposition ofmatrixes. The procedure of initial and 2 epochal measurements of deformations,the procedure of the data processing, and the results of the deformation monitoringare described.
