“…Given these parameters and each value for the relative position of the neutral axis, the tension reinforcement area was dimensioned from Equation (8). With the tensioned reinforcement values, the bending moment resistance of the cross section was obtained for each neutral axis position by Equation (6). Then, the reliability analyzes were performed for the different designed cross-sections in the previous step.…”

This paper presents a study about safety of reinforced concrete beams subjected to bending moment and designed with the partial safety factors proposed by ABNT NBR 6118:2014. The main goal was to assess the uniformity in the safety of the beams considering different values for the neutral axis position and the load ratio, by using the Reliability Theory. A simplified procedure to calibrate the partial safety factors was proposed taking into account the nature of each random variable and a target reliability index. From the analysis of the results, an alternative method for the design of reinforced concrete beams was also proposed, in which safety is guaranteed by the using of a probability of failure instead a set of partial safety factors. The results showed the lack of uniformity in the safety of the beams design with de constant set of partial safety factors. The procedures of design and calibration of the new safety factors were capable of to give uniformity to the safety of the beams and to achieve the proper structural configuration with the required safety level.

“…As an example, in the works of Han [16] and Ellingwood [17], the case of several kinds of load modeling is studied in system reliability. To deal with large nonlinear systems, Mohamed et al [5] proposed to linearize the mechanical model in order to simplify the reliability analysis and hence to increase the performance of the method.…”
