ABSTRACT
In the calibration of partial safety factor of steel reinforcement bars conducted in this study, necessary parameters (i.e. steel diameter, area, yield strength, ultimate strength, and elongation) needed for the calibration were obtained from the steel testing laboratory, Department of Civil Engineering, Ahmadu Bello University Zaria. The test results were analyzed in accordance with Eurocode, JSCC and ISO standards with the aid of Microsoft Excel, SPSS, EasyFit and COMREL software packages. The steel reinforcement parameters were checked for outliers and the PDF of the steel reinforcement parameters were analyzed using the Kolmogorov-Smirnov goodness of fit test. The result from the analysis showed that the probability density function of the steel reinforcement bars diameter follows a Log-Normal distribution, the yield strength and ultimate yield strength fits a Gumbel(Min) and Gumbel(Max) distribution respectively. Also, the calibrated design values of the steel reinforcement bar diameter, yield and ultimate strength are 2.167 (8.7mm), 398.33N/mm2 , 842.7N/mm2 respectively with a reliability index value of 3.805 and probability of failure of 7.08E-5 which yielded a partial safety factor 1.07(0.93) with a characteristics value of approximately 426N/mm2 . Hence, it was recommended that the characteristic strength of the steel reinforcement bars should be set to 426N/mm2 with a safety factor of 0.93(1.07)
