Information-Measurement System for Experimental Investigation of Reinforced Concrete Beams

This article describes the information-measurement system created by the author for studying the behavior of reinforced concrete beams subjected to the action of static loads. During the experimental tests, the strains
$\varepsilon_{\mathrm{c}}$
were measured and the stresses
$\sigma_{\mathrm{c}}$
were calculated in the compression and tension zones of reinforced concrete beams, the vertical displacements in characteristic points, the applied pressure in the press, the temperature t were measured and recorded, the force F was calculated at the different loading stages, the appearance and development of cracks was tracked. The unified information-measurement system consists of machines, specialized devices (UPM 100, Spider 8) and various sensors connected to them (strain gauges, inductive displacement transducers, pressure sensors, temperature sensors). Data collection was provided with the Catman Professional 5.0 program of the HBM Company. The obtained results were processed with the program product Microsoft Excel.
