DEFORMATION MEASUREMENT OF A STRUCTURE WITH CALCULATION OF INTERMEDIATE LOAD PHASES

At the Centre for Geodesy of the University of Maribor, Slovenia, we engaged in the measurement and analysis of displacements for the last ten years. We wanted to find the connections between the displacements and the applied loads. Therefore, reliable and accurate results were needed. A reinforced-concrete plate was loaded to 42 kN in pre-calculated steps and the resulting deformations measured by three independent methods. The results were compared to analytical ones. The analyses and calculations of the most suitable method were implemented. An electronic tacheometer, photogrammetry and a pressure length transducer on the hydraulic cylinder were used.
