Abstract
The tensile test is one of the most important of engineering tests for concrete reinforcement bars. In this paper, steel tensile tests were carried out with test specimens of CB-300V rebar of VINAUSTEEL Company with diameters of 12, 14 and 16mm. The process of endurance testing according to TCVN197-1:2014 - method B with WA-1000 testing machine. The values of “upper yield strength”, “lower yield strength”, “tensile strength” were determined through experiment with the fracture subjects respectively. The effect of the loading rate (stress rate) on those values was analyzed, based on that, authors suggest the appropriate loading rate range.
