Sažetak
This research is of theoretical and experimental character which elaborates yield point of concrete steels based upon the known alloy chemical composition. The experimental part of the research was realised in the Split steel factory which produces concrete steels from the waste iron. The theoretical part of this study – the mathematical modelling was carried out by means of the software package MatLab. The research resulted with a scientific and practical contribution. By using mathematical modelling the accuracy of the so far known initial correlation for estimation of the yield point is improved. by 8.5 %. Using this correlation shall enable reduction of the concrete steel production cost because it is possible to avoid expensive tests of the strength and mechanical properties by the tensile tests.
