Improvement of the methodology for plotting a stress-strain diagram for concrete with indirect reinforcement in the form of cross welded mesh
Setting the indirect reinforcement in the form of cross welded mesh is one of the effective ways to increase the strength and deformation characteristics of compressed concrete. When performing engineering calculations of structures with indirect reinforcement, in order to ensure the required reliability, it is necessary to use the design values of the strength of materials. At the same time, initially the calculation formulas were derived and analyzed for the experimental average strength values, which are significantly higher than the design ones. Based on the results of the calculations, it was found that a simple substitution of the calculated strength values in the formulas leads to an overestimation of the strength and ultimate compressibility values of concrete with indirect reinforcement.
