Abstract

In this research, samples of locally manufactured and imported reinforcing steel with different diameters 14 and 16 mm were studied by conducting tensile test, which is an important mechanical test to know the properties of mechanical materials and study their behaviour by under loading two samples of each type using a general tensile testing machine type (SHUMIDUZ –UH2000). The results obtained from this test were used to find a set of properties represented in the ultimate tensile strength (σUTS), yield strength or yield point (σy), yield strain(e), and maximum strain (eMax), and there was a set of properties such as elastic modulus (E), Toughness modulus (T) and modulus of Resilience (Ur) that were mathematically calculated. The real stress and real strain for all samples were calculated too. The engineering stress and the engineering strain were presented by drawing the curves in order to show the difference. The results obtained from the tensile test showed that all samples were of steel reinforcement with protrusions of an average resistance (T30) where the yield stress values were 340-406 N/mm2, and the tensile strength values were 574-673 N/mm2which conforms to the Libyan Standard No. 75 of 2013 for concrete reinforcing steel bars. The results also showed the convergence of local samples with the imported samples.
