Modes of Failure Analysis in Reinforced Concrete Beam Using Laser Scanning and Synchro-Photogrammetry - How to apply optical technologies in the diagnosis of reinforced concrete elements?
Abstract
The following paper reveal the limitations and possibilities of terrestrial laser scanning technology adaptation in diagnostics of reinforced concrete beams. 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. 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. Beam has been properly prepared in order to maximize quality of obtained data. Reinforced concrete beam was progressively overloaded and finally failure by shear and bending. The failure process was attentively tracing and registering by terrestrial laser scanner during the survey. Collected data were post-processed using the software dedicated to scanner (Leica Cyclone) and moreover GPL software (MeshLab). Also in order to validate results, separately resistance strain gauge survey was provided. Furthermore, authors used non-meter synchronous digital cameras to perform a Photogrammetric Process. Main subject of this particular paper is to demonstrate efficiency of laser scanning for the diagnosis of reinforced concrete beams deterioration. Analysis of the data from survey allow to assess whether the displacement can be measure with accuracy not worse than 1 mm. Efficiency of TLS can be a great advantage in multiplied studies or inspections of structural elements. As a result of authors’ research it was achievable to create the consistent procedure to particularize modes of failure in reinforced concrete beams.
