Reinforced concrete beam was progressively overloaded and finally failure by shear and bending. Beam has been properly prepared in order to maximize quality of obtained data. Research was carried out at the Regional Laboratory of Structural Engineering at Gdansk University of Technology, as a part of experiments, effectuate by Faculty of Civil and Environmental Engineering. In this paper, authors present potential spectrum of TLS use in modes of failure analysis of R-C beams and determines under which conditions the laser technologies might be applied. The following paper reveal the limitations and possibilities of terrestrial laser scanning technology adaptation in diagnostics of reinforced concrete beams. Scanning was performed from one stable measurement station to avoid in processing the effect of correlation errors (matching and linking) of ScanWorld. In the description of the experiment there are six stages of measurement mentioned for the reinforced concrete beam: from the zero condition (no force), through intermediate conditions up to the stage of destruction. However, the principal subject of this paper is to show the usefulness of laser scanning for the analysis of reinforced concrete beams damages and authors of this paper focused on this subject. In order to verify results, the independent recording of beam deflection with use of extensometer and the recording with non-meter synchronous digital cameras were carried out, photos from these cameras were subjected to photogrammetric processing. Development of scanning effects was performed using Leica Cyclone software and MeshLab. The process of press impact on the reinforced concrete beam was recorded using terrestrial laser scanner. As part of experiments carried out at the Regional Laboratory of Construction (at Gdansk University of Technology), reinforced concrete beams were subjected to destruction by bending and by shear. The authors present an analysis of the possibility to assess deformations and mode of failure of R-C beams using terrestrial laser scanning.
