ResumoTensile behaviour was investigated for reinforcing steel bars used in the Nigerian Construction Industry; this was done to ascertain the level of conformity of the tested parameters with the standards.A total of thirteen ( 13) companies operating in Nigeria were considered and ( 19) nineteen samples selected randomly with each sample containing ten specimens which were used in the tests.Out of the nineteen ( 19) samples, thirteen (13) were locally produced in Nigeria, while six (6) were imported.Thus, a total of 190 specimens were used for the experiment.It was found that eleven ( 11) samples out of the nineteen ( 19) samples examined failed to meet the requirements of BS4449:1997 in respect of the characteristic strength.In case of the Ultimate: Yield ratio, while only one (1) out of the nineteen (19) samples did not record the minimum values of 1.25 as prescribed by the code.
